The manual type pilot rope ladder reel has the advantages of being simple in structure, reasonable in design, convenient to use, good in self-locking effect and the like.

The invention discloses a lifting device for a stand-steering forklift. The stand-steering forklift comprises a forklift body and the lifting device, the front side of the forklift body is fixedly connected with the lifting device, a moving outer frame is mounted on the front side of the lifting device, a forklift frame is fixedly connected at the bottom of the moving outer frame, a control box isfixedly connected at the top of the lifting device through a supporting frame, moving wheels are mounted at the bottom of the forklift body, and a rotating motor is fixedly connected inside the lifting device and rotatably connected with a first belt wheel through an output shaft. The invention relates to the technical field of the stand-steering forklift. The objective of lifting and lowering anarticle is achieved, and the article can be clamped during lifting and lowering, so that danger caused by the fact that goods may fall from a fork plate when the forklift jolts during movement is reduced, and working efficiency of the forklift is improved; a lubricating device is arranged inside the lifting device, so that the lifting device can be ensured to run more smoothly.

The invention relates to a pipe support frame. According to the technical scheme, the pipe support frame comprises a support case body, a left support rod and a right support rod which are distributed in a crossed mode and are capable of moving on the support case body are arranged on the support case body, the upper end of the left support rod and the upper end of the right support rod are each provided with a support wheel, and the lower end of the left support rod and the lower end of the right support rod are both connected with a moving driving mechanism which is arranged in the support case body and used for driving the left support rod and the right support rod to conduct synchronous moving; when the left support rod and the right support rod conduct the synchronous moving under the action of the moving driving mechanism in the support case body, the support wheels corresponding to the upper end of the left support rod and the upper end of the right support rod can be made to be lifted up and dropped down relative to the support case body. The pipe support frame is compact in structure, the positioning accuracy of a supported pipe can be greatly improved, adjustment of the consistency of the center distance to the supported pipe is achieved, and safety and reliability are achieved.

A road bridge width limiting device is composed of a flip plate, a support spring, a limit member, a pull rod and an outer support spring. The bottom of the moving part is mounted with a moving wheelthrough a connecting part and a rotating shaft, and the outside of the moving shaft is provided with threads, and the moving shaft is installed in the inside of the rotating part through threads; theinsert on the inner side of the tensioning member is installed inside the insert sliding groove on the inner side of the rotating member in an inserting manner, and a manual lever is mounted on the outer edge position of the tension member by welding, and the outer end of the manual lever is provided with a limited position lever through a mounting hole. The rotating part here plays the rotationalpower transmitted by the receiving manpower., the rotating member transmits the power to the moving shaft through the internal thread, so that the moving shaft drives the moving member to move to different positions, thereby limiting the width of the road or the bridge, and the insert in the middle position of the rotating member is embedded into the inside of the fixed groove installed in the middle position of the main body.

The invention discloses a safe lithium battery transportation device facilitating taking and putting of lithium batteries and relates to the technical field of lithium batteries. The safe lithium battery transportation device comprises an outer frame. The two sides of the bottom of the inner wall of the outer frame are rotationally connected with lead screws correspondingly through a base; the two sides of the surface of each lead screw are connected with moving blocks in a threaded mode correspondingly; the tops of the moving blocks are rotationally connected with a supporting plate through connecting rods correspondingly; the two sides of the top of the supporting plate are both fixedly connected with vertical plates; the opposite sides of the two vertical plates are directly and slidably connected with a pushing plate; the two sides of the top of the pushing plate are both rotationally connected with rotating rods; one ends of the rotating rods are rotationally connected with sliding blocks; and first springs are fixedly connected between one sides of the sliding blocks and one sides of the vertical plates. According to the safe lithium battery transportation device facilitating taking and putting of the lithium batteries, the device can rise and fall, taking and putting of the lithium batteries are facilitated so that people can conveniently use the lithium batteries, the labor amount of workers is decreased, the lithium batteries are prevented from being damaged in the transportation process, the property loss is avoided, and the practicability of the device is improved.
