Railway construction machine guard rail hoisting device and rail replacing locomotive guard rail hoisting device

Abstract

The invention relates to a railway construction machine guard rail hoisting device and a rail replacing locomotive guard rail hoisting device, comprising a guard rail hoisting apparatus and an anti-loosing device, wherein the guard rail hoisting apparatus is arranged below a railway construction machine, such as a rail replacing operation vehicle traveling mechanism vehicle body and can integrally lift and transversely move a railway construction machine vehicle body, and the anti-loosing device is arranged on each steering frame of a steel rail traveling machine to enable the steering framesand the vehicle body to be vertically fixed into a whole. The guard rail hoisting apparatus comprises an elongated supporting body, a guard rail suspension bracket and a control device, wherein the supporting body is fixedly suspended below the vehicle body through the guard rail suspension bracket, the control device is used for controlling the movement of the supporting body, a guard rail assembly is respectively arranged at both ends below the supporting body, the control device comprises two telescopic guard rail vertical oil cylinders and telescopic guard rail integral swinging oil cylinders, and the guard rail suspension bracket is provided with two downward stretching struts which are respectively hinged with both ends of the supporting body through two guard rail support rods. Theinvention enables a railway which needs to be born but is not completely fixed to be kept in an upright state in the construction process, farthest prevents the occurrence of a turning-way accident, and also enables the turning-way railway construction machine to rapidly hoist and safely reset.

Description

technical field [0001] The invention relates to a running machine of a railway construction machine, in particular to a guard rail recovery device used for replacing a seamless line rail changing operation vehicle. Background technique [0002] At present, in the prior art, the running mechanism of the railway construction machinery is not equipped with a special guard rail device to ensure the upright state of the track and the constant distance between the two rails. The rails are inevitably in a state of being unfixed or not fully fixed. In this state, the rails are prone to inclination or deviation, and the distance between the two rails is difficult to keep constant. It is very easy to fall off the road during the operation. Once it falls off the road, you can only use large jacks or long-distance transportation of large-scale lifting machinery. The whole lifting process is complicated and the cycle is long.

[0002] At present, in the prior art, the running mechanism of the railway construction machinery is not equipped with a special guard rail device to ensure the upright state of the track and the constant distance between the two rails. The rails are inevitably in a state of being unfixed or not fully fixed. In this state, the rails are prone to inclination or deviation, and the distance between the two rails is difficult to keep constant. It is very easy to fall off the road during the operation. Once it falls off the road, you can only use large jacks or long-distance transportation of large lifting machinery. The whole lifting process is complicated and the cycle is long.

[0003] For example, the present railway rail changing machinery is not equipped with guard rail machinery, as Chinese patents CN2263610Y, CN2871617, CN2510526Y, and CN1152169C disclose different types of rail changing machinery suitable for different purposes. After most of the fasteners of the old rail are removed by the side of the rail, the old rail is continuously moved out of the rail support groove section by section while the machine is walking, and the new rail is continuously placed in the rail support groove section by section. In the operation mode, the front and rear wheel sets of the work vehicle run on the new rail or the old rail respectively. At this time, the new rail or the old rail are not fastened by fasteners. Due to the occurrence of lateral and longitudinal displacements, large forces must be borne. Both the new rails and the old rails are difficult to maintain an upright position. Once the rails are tilted or the gauge is too large, it is easy to cause construction vehicles such as working vehicles to fall or tilt. For safety accidents such as overturning, the general treatment method requires the help of other equipment to complete the reset process, such as using a crane to hoist the construction machinery such as the work vehicle as a whole, manually cooperate to reset the wheel set, or use multiple hydraulic jacks in different parts. The construction machinery support is lifted to a certain height, and then the wheel set is reset manually. During this process, since the bogie in the prior art is not fixed in the vertical direction, the bogie part Usually it needs to be jacked up again to complete the alignment and reset of the bogie wheel set and the track

Since the car body itself does not have the function of self-recovery, the requirements for the site and equipment of the lifting operation are relatively high, and the number of workers in the lifting process is large, so it is difficult to guarantee the safety of the construction personnel. Generally, the track switching task cannot be completed as scheduled, which affects the normal opening of the line

[0004] The hoisting and recovering methods in the prior art all have the disadvantages of long working time and dangerous working process, especially the hoisting method needs to urgently transport a large crane to the site, the time is tight and the site is limited, which brings great difficulties to the construction
