Electric rail clamping device of throw-off carriage

Abstract

The invention discloses an electric rail clamping device of a throw-off carriage. The electric rail clamping device comprises a rail clamping device support arranged on one side of the throw-off carriage, wherein rail clamping tongs and an electric hydraulic pushing rod pushing device which are in power connection are installed on the rail clamping device support, a large connecting rod is hinged between the top of the rail clamping device support and a pushing rod on the top of the electric hydraulic pushing rod pushing device, an upper connecting rod and a main supporting rod are sequentially hinged below the large connecting rod, and the outer wall of the main supporting rod is sleeved with a spring. The rail clamping tongs comprise two sets of lower connecting rods which are hinged to the bottom end of the main supporting rod at the same time, and two sets of clamping blocks which are used for clamping a rail are symmetrically hinged to the bottom ends of the two sets of lower connecting rods. According to the electric rail clamping device, the electric hydraulic pushing rod pushing device is utilized as a power source, on the basis of the lever principle, the lifting force is transmitted to the rail clamping tongs, clamping of the rail is achieved, the safety and reliability are high, in addition, due to the fact that the rail clamping tongs are only provided with one positioning shaft, the position of the positioning shaft can be floated according to the position of the rail, on the premise that the straightness error of the rail is large, the clamping action can be reliably completed, and the applicability is high.

Description

technical field [0001] The invention relates to a rail clamp, in particular to an electric rail clamp for an unloading vehicle. Background technique [0002] The belt conveyor unloading vehicle is a device that can continuously unload materials at any point. Because the component force in the running direction generated during the material lifting process is to make the unloading truck slide in the running direction, in order to ensure its reliable positioning and complete the unloading work under heavy load conditions, the general unloading truck is equipped with brakes. In practical applications, it often occurs that the wheels do not roll but slide on the track after braking, which seriously affects the normal operation of the equipment and may endanger the safety of people and equipment. [0003] Therefore, it is necessary to add a rail clamp on the unloading car. Although there is a manual type of rail clamp in industrial applications, it cannot meet the requirements o...

Problems solved by technology

Because the component force in the running direction generated during the material lifting process is to make the unloading vehicle slide in the running direction, in order to ensure its reliable positioning and complete the unloading work under heavy load conditions, the general unloading vehicle is equipped with a brake. In practical applications, it often occurs that the wheels do not roll but slide on the track after braking, which seriously affects the normal operation of the equipment and may endanger the safety of people and equipment

[0003] Therefore, it is necessary to add a rail clamp on the unloading truck. Although there is a manual type of rail clamp in industrial applications, it cannot meet the requirements of automatic control of the system, and it is very inconvenient to operate on a running unloading truck. and there is a certain risk

However, ordinary electric or hydraulic rail clamps have the defects of complex structure, poor operation reliability, and can not be well adapted to the actual supporting needs of unloading trucks.
