Abstract
The invention relates to a clamping device for locomotive haulage. The clamping device is connected with a transportation vehicle and comprises an oil cylinder seat, a hydraulic oil cylinder, a clamping plate, a hydraulic system and a control system, wherein the hydraulic oil cylinder is arranged on the oil cylinder seat; the clamping plate is connected with a piston rod of the hydraulic oil cylinder; the hydraulic system is used for controlling the hydraulic oil cylinder; the clamping plate can stretch out or retract through the hydraulic oil cylinder; the clamping devices are arranged in pairs; and each clamping plate stretches or retracts towards the steel wheel direction of a locomotive to be clamped. The clamping device can reduce operation process and improve work efficiency, is easy to operate, reduces work difficulty and improves personal safety of operators.
Description
Technical field
the present invention relates to the transport field of locomotive, particularly relate to a kind of locomotive transportation fixing device.
Background technology
are to realize the fixedly purpose of locomotive through on the guide rail of transport trolley, placing the mode car of covering the rail device in the locomotive transportation in the prior art.After waiting locomotive to be placed into the assigned address of transport trolley at every turn; Creep into by the operator and will cover under the locomotive under the steel wheel that the rail device is placed into locomotive; Owing to cover between rail device and the locomotive gappedly, locomotive can be along with the starting of transport trolley brake and move forward and backward in transportation, covers the rail device and causes covering the rail device and be difficult to take off owing to the steel wheel of locomotive pushes behind the transportation destination simultaneously; Spur steel wheel that locomotive makes locomotive again and cover the rail device and separate, because this is that operation is very inconvenient under the locomotive car.This operating mode inefficiency, operational difficulty, job safety can not guarantee simultaneously.
Summary of the invention
the purpose of this invention is to provide a kind of locomotive transportation fixing device.
For achieving the above object, the technical scheme that the present invention adopts is:
a kind of locomotive transportation fixing device; This fixing device is connected on the transport trolley; It comprises oil cylinder seat, be installed in hydraulic ram, the clamping piece that is connected with the piston rod of described hydraulic ram on the described oil cylinder seat, be used to control the hydraulic efficiency pressure system and the control system of described hydraulic ram; Described clamping piece can stretch out or withdraws through described hydraulic ram; Described fixing device is provided with in pairs, and the steel wheel direction of direction towards locomotive to be clamped of stretching, contract of described clamping piece.
preferably, the bottom of described clamping piece is provided with guide rail.
preferably, described oil cylinder seat is through bolt or be weldingly fixed on the described transport trolley.
preferably, described clamping piece is connected through the oil cylinder bearing pin with the piston rod of hydraulic ram.
preferably, described hydraulic efficiency pressure system is provided with hydraulic lock and overload protection.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, reduces operating process, improve operating efficiency;
2, simple to operate, reduce task difficulty;
3, raising operator's personal safety.
Description of drawings
Accompanying drawing 1 is the structural representation of fixing device among the present invention;
Accompanying drawing 2 is the scheme drawing of the present invention and locomotive transportation;
Scheme drawing when
accompanying drawing 3 is the work of many groups of the present invention.
wherein: 1, oil cylinder seat; 2, hydraulic ram; 3, clamping piece; 4, hydraulic efficiency pressure system; 5, guide rail; 6, oil cylinder bearing pin; 7, transport trolley; 8, steel wheel; 10, fixing device.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
A kind of locomotive transportation fixing device that
are as shown in Figure 1, it comprises oil cylinder seat 1, hydraulic ram 2, clamping piece 3, hydraulic efficiency pressure system 4 and control system.Wherein: oil cylinder seat 1 can be fixed on the transport trolley 7 through modes such as bolted connection or welding; The cylinder body of hydraulic ram 2 is fixed on the oil cylinder seat 1, and the piston rod of hydraulic ram 2 is connected with clamping piece 3 through oil cylinder bearing pin 6, and the bottom of clamping piece 3 is provided with guide rail 5 as guiding.Clamping piece 3 can be through the operating hydraulically operated oil cylinder 2 of hydraulic efficiency pressure system oil-feed, fuel-displacedly stretch out or withdraw.
in general, fixing device 10 double-type settings, a pair of clamping piece 3 stretch out or the direction of withdrawing towards steel wheel 8 directions of locomotive to be clamped, as shown in Figure 2.
in addition, oil cylinder seat 1, clamping piece 3 will have enough intensity and rigidity, oil cylinder seat 1 is the benchmark of this device, relative position is extremely important, can position through the distance of clamping piece 3 steel wheel 8 of locomotive to the transport trolley 7; The power that hydraulic efficiency pressure system and hydraulic ram 2 provide clamping piece 3 to stretch out or withdraw, hydraulic efficiency pressure system has the hydraulic lock function simultaneously, simultaneously over-voltage protecting function will be arranged, and accomplishes to clamp the steel wheel 8 of locomotive, locomotive is not produced again and damages.
Be explained in detail in the face of the operation of locomotive transportation fixing device down: may further comprise the steps:
1, locomotive is placed into the assigned address on the transport trolley 7;
2, hydraulic ram 2 locks hydraulic lock through the steel wheel 8 that hydraulic efficiency pressure system stretches out clamping piece 3 to withstand locomotive;
3, transport trolley 7 walkings put the locomotive transportation in place;
4, hydraulic ram 2 makes clamping piece 3 withdrawals through hydraulic efficiency pressure system, and clamping piece 3 is separated with the steel wheel 8 of locomotive;
5, locomotive leaves and begin next construction circulation.
are as shown in Figure 3, and the logarithm of fixing device 10 can be set through required requirement.
the present invention uses hydraulic ram 2 to be installed on the transport trolley 8, with the fixing modes such as steel wheel 8 of locomotive of clamping piece 3, can make locomotive in the entrucking and the process of unloading, reduce operation simultaneously, and simple to operate, increases conveying efficiency.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
