Problems solved by technology

However, this tripod is not only difficult and time-consuming to bind, but also has poor support stability and safety.
If the field of use is uneven, the stability and safety of this bundled tripod will be worse. In the lifting operation, once the tripod collapses, it will cause an accident.

Embodiment 1

[0031] Example 1: from figure 1 It can be clearly seen that the portable jack bracket lap fixing frame includes a central standpipe 11, three fork pipes 12 symmetrically vertically fixed at the bottom end of the central standpipe 11, and a limit plate 13 arranged at the top end of the central standpipe 11. The frame body 1; each fork tube 12 of the frame body 1 is respectively equipped with a scaffold rotating buckle 2 for the convenient insertion and fixing of the support rod.

[0032] The limiting plate 13 is provided with three limiting notches 14 corresponding to the number of the fork tubes 12 .

[0033] The overlapping fixing frame of the portable jack bracket in this embodiment can be used for building a tripod bracket. When in use, only need to insert three support rods respectively into the pipe buckles 21 of the scaffold rotating buckle 2 arranged on the three fork pipes 12, and the tops of the three support rods are respectively embedded in the three limit plates 1...

Embodiment 2

[0034] Example 2: from figure 2 It can be clearly seen that the basic structure of the portable jack bracket overlapping the fixing frame is the same as that of Embodiment 1, the only difference being:

[0035] A scaffold cross buckle 3 is installed on the central riser 11 of the frame body 1 .

[0036] In this embodiment, the construction method of the portable jack bracket overlapping the fixed frame for the tripod bracket is the same as that of Embodiment 1. And the scaffolding cross buckle 3 that is provided with on the central riser 11 can be installed a steel pipe that can be used as crossbeam to insert and fix.

[0037] In addition to the same function as that of Embodiment 1, the portable jack bracket lap joint fixing frame of this embodiment can also be conveniently built into a beam-type support frame with a certain span by using two tripods built in this embodiment. , its method is: a steel pipe is inserted in the scaffolding cross buckle 3 of two tripod center r...

Embodiment 3

[0038] Example 3: from image 3 It can be clearly seen that the basic structure of the portable jack bracket overlapping the fixing frame is the same as that of Embodiment 1, the only difference being:

[0039] The nozzle 15 at the top of the central riser 11 is equipped with a locking mechanism 4 that can close the three limiting notches 14 on the limiting plate 1 to prevent the support rod from slipping out of the limiting notches 14 .

[0040] The locking mechanism 4 such as Figure 4 As shown, it consists of a ratchet cylinder 41, a lock plate 42, a manipulation member 43 and a top cover 44;

[0041] The ratchet cylinder 41 has a circular tubular structure, the middle part of the ratchet cylinder 41 is provided with a protruding ratchet ring 411, and the upper part of the ratchet cylinder 41 is provided with a threaded end 412 that can be threaded with the top cover 44 to prevent the lock plate 42 from moving axially. The lower part of the barrel 41 is provided with an i...

Abstract

The invention discloses a portable overlapping fixing bracket for a jack bracket. The fixing bracket is characterized by comprising a bracket body consisting of a central vertical pipe, at least three Y-type pipes symmetrically fixed at the bottom end of the central vertical pipe and a limiting plate at the top end of the central vertical pipe, wherein scaffold rotating buckles are arranged on the Y-type pipes of the bracket body respectively and used for inserting and fixing support rods conveniently; and the limiting plate is provided with support rod limiting notches of which the number corresponds to that of the Y-type pipes. The scaffold rotating buckles on each Y-type pipe can conveniently adjust the extension length of each support rod according to the topographical condition and can rapidly fix the support rod with the fixing bracket in a drawing mode, so that the central vertical pipe of the fixing bracket is kept in a vertical state, the stable hoisting and safe operation ofa jack hung on the bracket can be ensured. The fixing bracket can be stably erected on the ground within 3 minutes. The portable overlapping fixing bracket for the jack bracket has a simple structureand small size, is convenient to carry and very suitable for performing emergency rescue on an external field with complex topographical condition and enhances the timeliness of emergency rescue.

Description

technical field [0001] The invention relates to a bracket, in particular to a portable jack bracket overlapping fixing bracket. Background technique [0002] At present, light lifts such as chain hoists need to be temporarily used in many occasions, and a light lift needs to be equipped with a bracket for its installation and support when used. The existing light lift support frame generally adopts a tripod bracket built on site. This tripod bracket is usually built by binding three rods with ropes or wires. It has a certain bearing capacity and can be used for the temporary support use. However, this tripod is not only difficult and time-consuming to bind, but also has poor support stability and safety. If the field of use is uneven, the stability and safety of this bundled tripod will be worse. In the lifting operation, once the tripod collapses, it will cause an accident. Contents of the invention [0003] The technical problem to be solved by the present invention i...
