Description

Technical Field

[0001] The present invention relates to the technical field of long rail transportation, and particularly to an anti-sliding device for slopes and a long rail transport vehicle group. Background Art

[0002] With the development of railway technology, the requirements for the specified length and specifications of railway rails have changed. The transportation of long rails has become a major problem in railway transportation and an important research field in railway freight transportation.

[0003] Currently, the T11BK type long rail transport vehicle group is a commonly used special engineering vehicle group for laying continuous welded rails, which is used for the transportation, unloading, and receiving of long rails on Chinese standard gauge railways. When the long rail transport vehicle group performs rail unloading operations on a large slope line (generally with a slope exceeding 10%), after the side columns unlock the rails, the problem of the rails slipping along the slope will occur, bringing great danger to the on-site operations. In the prior art, when unloading rails on a large slope, the locking iron is not completely unlocked, and the rails are controlled by the locking iron to achieve the unloading of the rails.

[0004] However, controlling the rails by the locking iron, on the one hand, it is difficult to control the force; on the other hand, the rubber under the locking iron rubs against the rails, which easily causes the rubber on the locking iron to fall off. The rails get out of control and slide down when unloading because they do not get the corresponding frictional force, thus bringing great danger to the on-site operations. Summary of the Invention

[0071] Specifically, the support side column 110 is vertically installed on the safety vehicle 200, and the fixed connection manner between the support side column 110 and the safety vehicle 200 is not specifically limited herein. Optionally, the support side column 110 is welded to the safety vehicle 200, or the support side column 110 is fixedly connected to the safety vehicle 200 through fasteners, which is convenient for the separation and disassembly of the support side column 110 and the safety vehicle 200.

Wear-resistant nylon 140 is inlaid in the clamping jaws of the clamping mechanism 130. When the clamping mechanism 130 clamps the long rail, the wear-resistant nylon 140 can increase the friction between the clamping mechanism 130 and the long rail, preventing the long rail from slipping from the clamping mechanism 130 and causing a safety accident.

[0073] In a possible implementation manner, the ramp anti-slip device may further include: a lifting mechanism 150. The lifting mechanism 150 is installed on the support side column 110 and is connected to the rail clamping beam 120, and the lifting mechanism 150 is used for driving the rail clamping beam 120 to move in the height direction of the support side column 110.

[0074] Specifically, the lifting mechanism 150 can be installed at any position on the supporting side column 110, depending on the specific situation of the work site. The lifting mechanism 150 is connected to the rail clamping beam 120 and is used to drive the rail clamping beam 120 to move up and down in the height direction of the supporting side column 110.

[0075] In the above embodiment, the lifting mechanism 150 includes: a handle 151, a first rotating shaft 152, a gear set 153, and a lead screw 154. The handle 151 is fixedly connected to the first rotating shaft 152. The first rotating shaft 152 is connected to the gear set 153. The gear set 153 is connected to the lead screw 154. The lead screw 154 is connected to the rail clamping beam 120. The handle 151 is used to drive the first rotating shaft 152, the gear set 153, and the lead screw 154 in sequence to drive the rail clamping beam 120 to move in the height direction of the supporting side column 110.

[0076] Specifically, the handle 151 and the first rotating shaft 152 can be fixedly connected or integrally formed. The first rotating shaft 152 is meshed and connected to the gear set 153. It should be noted that the gear set 153 is composed of one or more meshing gears. The gear set 153 is connected to the lead screw 154. The lead screw 154 is connected to the rail clamping beam 120. The staff can rotate the handle 151. The handle 151 drives the first rotating shaft 152. The first rotating shaft 152 drives the gear shaft 153. The gear set 153 drives the lead screw 154. The lead screw 154 drives the rail clamping beam 120 to move up and down in the height direction of the supporting side column 110.

[0077] In the above embodiment, the supporting side column 110 includes: a side column main body 111, a second rotating shaft 112, a base 113, and a fastener 114. The base 113 is fixed on the safety vehicle 200. The side column main body 111 is connected to the base 113 through the second rotating shaft 112.

Corresponding first mounting holes and second mounting holes are provided on the side column main body 111 and the base 113. The fastener 114 is inserted into the first mounting hole and the second mounting hole to fix the side column main body 111 and the base 113.

[0078] Specifically, the base 113 is fixedly connected to the safety vehicle 200 by bolts, facilitating the separation and disassembly of the support side column 110 from the safety vehicle 200. The side column main body 111 is connected to the base 113 through a second rotating shaft 112. The axis of the second rotating shaft 112 extends along the height direction of the side column main body 111, and the side column main body 111 can rotate through the second rotating shaft 113. Corresponding first mounting holes and second mounting holes are provided on the side column main body 111 and the base 113. The fastener 114 is inserted into the first mounting hole and the second mounting hole to fix the side column main body 111 and the base 113. The fastener 114 restricts the relative rotation between the side column main body 111 and the base 113. When it is necessary to rotate and support the side column 110, the fastener 114 is removed. Conversely, when it is necessary to fix the support column 110, the fastener 114 is inserted.

[0079] In the above embodiment, the rail clamping beam 120 includes: a slideway beam 121, a fixed sliding sleeve 122, and a transmission chain mechanism 123.

The fixed sliding sleeve 122 is sleeved on the support side column 110 and connected to the lifting mechanism 150. The transmission chain mechanism 123 is fixedly connected to the clamping mechanism 130, and the transmission chain mechanism 123 is used to drive the clamping mechanism 130 to move in the length direction of the slideway beam 121.

[0081] Specifically, the first end of the slideway beam 121 is fixedly connected to the fixed sliding sleeve 122, and the second end of the slideway beam 121 is suspended. The fixed sliding sleeve 122 is sleeved on the support side column 110 and connected to the lifting mechanism 150. The lifting mechanism 150 drives the fixed sliding sleeve 122 to move in the height direction of the support column 110. Furthermore, the rail clamping beam 120 can move up and down in the height direction of the support column 110. The transmission chain mechanism 123 is installed in the length direction of the slideway beam 121. The clamping mechanism 130 is fixedly connected to the transmission chain mechanism 123, and the transmission chain mechanism 123 drives the clamping mechanism 130 to reciprocate in the length direction of the slideway beam 121.

[0082] In the above embodiment, the transmission chain mechanism 123 includes: a chain 123.1, a driving wheel 123.2, a driven wheel 123.3, and a crank 123.4. The chain 123.1 is connected between the driving wheel 123.2 and the driven wheel 123.3. The clamping mechanism 130 is fixed on the chain 123.1. The crank 123.4 is connected to the driving wheel 123.2 to drive the driving wheel 123.2 to rotate.

[0083] Specifically, the driving wheel 123.2 and the driven wheel 123.3 are mounted at both ends of the slideway beam 121. The driving wheel 123.2 and the driven wheel 123.3 are connected by a chain 123.1. The clamp mechanism 130 is fixedly connected to the chain 123.1. The crank 123.4 is connected to the driving wheel 123.2 to drive the driving wheel 123.2. When the crank 123.4 is rotated, the rotation of the crank 123.4 drives the driving wheel 123.2, and the driving wheel 123.2 drives the chain 123.1 and the driven wheel 123.3 to move together. Furthermore, the clamp mechanism 130 fixed to the chain 123.1 can reciprocate in the length direction of the slideway beam 121.

[0084] In the above embodiment, the clamp mechanism 130 includes: a hydraulic pump 131, a hydraulic cylinder 132, a clamp body 133, a retaining frame 134, and a connecting seat 135. The hydraulic pump 131 is installed on the side of the rail clamping beam 120. The hydraulic pump 131 is used to drive the hydraulic cylinder 132 to perform a piston movement. Both ends of the hydraulic cylinder 132 are hinged to the two clamping arms of the clamp body 133. The retaining frame 134 is connected to the two clamping arms. The retaining frame 134 is movably installed on the rail clamping beam 120. The connecting seat 135 is fixedly connected to the retaining frame 134, and the connecting seat 135 is connected to the chain 123.1.

[0085] Specifically, the hydraulic pump 131 is installed on the side of the rail clamping beam 120. The hydraulic pump 131 is connected to the hydraulic cylinder 132.

A retaining frame 134 is installed outside the clamp body 133. The retaining frame 134 is used to fix and movably install the clamp body 133 on the rail clamping beam 120. It should be noted that the movable installation means that it can move on the rail clamping beam 120 but will not fall off the rail clamping beam 120. A connecting seat 135 is fixedly connected to the retaining frame 134. The connecting seat 135 is connected to the chain 123.1. When the chain 123.1 moves, it will drive the connecting seat 135 to move, that is, drive the clamp mechanism 130 to move.

[0086] In the above embodiment, the clamp mechanism 130 further includes: a slideway roller 136. The slideway roller 136 is installed on the retaining frame 134 and is movably connected to the rail clamping beam 120.

[0087] Specifically, a pair of slideway rollers 136 are also installed on the retaining frame 134 and are movably connected to the rail clamping beam 120. When the clamp mechanism 130 moves on the rail clamping beam 120, the sliding is converted into rolling, reducing the friction force and preventing the clamp mechanism 130 from getting stuck on the rail clamping beam 120.

[0088] In the above embodiments, the clamp mechanism 130 further includes: a pressure gauge 137. The pressure gauge 137 is installed on the hydraulic pump 131.

[0089] Specifically, the pressure gauge 137 is installed on the hydraulic pump 131, which can monitor the output pressure of the hydraulic pump 131 in real time, facilitating the control of the clamping force of the clamp body 133.

[0090] The following provides a detailed description of the specific operation of the ramp anti-slip device provided by the embodiments of the present invention:

[0091] When loading long rails, remove the fastener 114, rotate the support pillar 110 to rotate the rail clamping beam 120 above the long rail to be loaded, insert the fastener 114 to fix the support pillar 110, rotate the handle 151, the handle 151 drives the first rotating shaft 152, the first rotating shaft 152 drives the gear set 153, drives the lead screw 154 through the gear set 153, the rotation of the lead screw 154 then drives the fixed sliding sleeve 122 to move up and down along the side pillar body 111, raise the rail clamping beam 120 to an appropriate height, rotate the crank 123.4 to drive the driving wheel 123.2, the driving wheel 123.2 drives the chain 123.1 and the driven wheel 123.3, thereby driving the clamp mechanism 130 to move left and right on the slideway beam 121, accurately move the clamp mechanism 130 to the long rail, start the hydraulic pump 131 to drive the hydraulic cylinder 132, open and clamp the rail with the clamp body 133, and observe the pressure gauge 137 to determine the required clamping force on ramps with different slopes for rail loading operations.

[0092] Those skilled in the art can understand that when unloading long rails with the ramp anti-slip device provided by the embodiments of the present invention, its specific operation and technical effects can be inferred and will not be elaborated here.

[0093] The ramp anti-slip device provided by the embodiments of the present invention realizes the loading and unloading of long rails by installing a support side column on a safety vehicle, connecting a rail clamping beam to the side of the support side column, and setting a clamp mechanism on the rail clamping beam. The clamp mechanism is used to clamp the long rail. The clamp mouth of the clamp mechanism is inlaid with wear-resistant nylon, which can increase the friction force on the long rail, prevent the long rail from slipping out of the clamp structure, and further reduce the risk of safety accidents at the construction site. The ramp anti-slip device provided by the present invention also realizes the loading and unloading of rails at any position by setting a movable support side column, rail clamping beam and clamp mechanism, and controls the clamping force of the rail by using a combination of a hydraulic pump, a hydraulic cylinder, a pressure gauge and a clamp, so that the rail will neither be damaged due to excessive clamping force nor slip due to too small clamping force.

[0098] For the long rail transport vehicle group provided by the embodiments of the present invention, by installing a support side column on the safety vehicle, connecting a rail clamping beam to the side of the support side column, and arranging a clamping mechanism on the rail clamping beam, the clamping mechanism is used to clamp the long rail to realize the loading and unloading of the long rail.

The wear-resistant nylon can increase the friction force on the long rail, prevent the long rail from slipping out of the clamping structure, and further reduce the risk of safety accidents occurring at the construction site. The present invention provides an anti-sliding device for slopes, and also realizes the loading and unloading of rails at any position by setting movable support side columns, rail clamping beams, and clamping mechanisms, and adopts a combination of a hydraulic pump, a hydraulic cylinder, a pressure gauge, and a clamp to control the clamping force on the rail, so that the rail will neither be damaged due to excessive clamping force nor slip due to too small clamping force.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0101] In the present invention, unless otherwise clearly specified or limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween.
