[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] This utility model provides a double-arm car tipper with a tilting hook arm, which is a more economical and simple multi-functional double-arm car tipper, reducing the weight of the car tipper and increasing the gross profit margin of the car tipper product.
[0036] The present invention relates to a double-arm trolley lever with a pitch hook arm, comprising a traveling wheel 1, a hook arm 2, a vehicle body 3, a traveling drive unit 4, a hook arm 5, two sets of linkage mechanisms 6, and two sets of pitch drive units 7, wherein the traveling drive unit 4 and the two sets of pitch drive units 7 are all fixed on the vehicle body 3.
[0037] One end of the hook arm 2 is hinged to the vehicle body 3 and is located at the rear end of the vehicle body 3; one end of the hook arm 5 is hinged to the vehicle body 3 and is located at the front end of the vehicle body 3; wherein, the front end is in the same direction as the front of the hook traction operation direction, and the rear end is in the same direction as the rear of the hook traction operation direction. In this embodiment, the operating direction is from left to right, with the right side of the vehicle body 3 being the front end and the left side being the rear end.
[0038] A set of pitch drive units 7 are connected to the hook arm 2 via a set of linkage mechanisms 6, and are used to drive the hook arm 2 to rotate around the hinge point between the hook arm 2 and the vehicle body 3.
[0039] Another set of pitch drive units 7 is connected to the hook arm 5 through another set of linkage mechanisms 6, and is used to drive the hook arm 5 to rotate around the hinge point between the hook arm 5 and the vehicle body 3.
[0040] Both the hook boom 2 and the hook boom 5 are pitching mechanisms, and the hook boom 2 and the hook boom 5 are installed on the same side of the vehicle body 3.
[0041] The other end of the hook arm 2 is equipped with a U-shaped groove for connecting with the coupler between two open wagons of a railway special vehicle, enabling the hooking and traction operation of the car-pulling machine. This U-shaped groove is compatible with railway couplers.
[0042] The other end of the hook boom 5 is equipped with a railway coupler, which is used to connect with the coupler of the last carriage of a railway special open wagon to realize coupling operation.
[0043] The traveling wheels 1 are located on both sides of the lower part of the vehicle body 3. The traveling drive unit 4 can be connected to the traveling wheels 1 through the existing gear mechanism. The traveling drive unit 4 and the gear mechanism drive the traveling wheels 1 to drive the entire car-pulling machine to move.
[0044] The width 'a' at the front end of the hook boom 2 is less than the distance 'A' between the two open wagon sections, such as... Figure 4 As shown. Simultaneously, when the hook boom 2 is tilted, the hook boom 2 must not interfere with the railway open wagon attachments. That is, by reasonably selecting the hinge point position of the hook boom 2, the maximum contour rotation radius r of the hook boom 2 is made smaller than the distance R from the railway open wagon attachments to the rotation center of the hook boom 2, such as... Figure 2 As shown.
[0045] The pitch drive unit 7 and linkage mechanism 6 of the hook boom 2 and hook boom 5 can have the same mechanism form.
[0046] The linkage mechanism 6 includes a first link and a second link. The output end of a set of pitch drive units 7 is connected to one end of the first link of the linkage mechanism 6, the other end of the first link of the linkage mechanism 6 is hinged to one end of the second link of the linkage mechanism 6, and the other end of the second link of the linkage mechanism 6 is hinged to the hook arm 2.
[0047] The output end of another set of pitch drive units 7 is connected to one end of the first link of another set of linkage mechanisms 6, the other end of the first link of another set of linkage mechanisms 6 is hinged to one end of the second link of another set of linkage mechanisms 6, and the other end of the second link of another set of linkage mechanisms 6 is hinged to the hook arm 5.
[0048] All of the above-mentioned first members are straight bars, and all of the second members are V-shaped bars with an opening angle greater than 90°.
[0049] Both of the aforementioned pitch drive units 7 use electric motors.
[0050] Working principle of this utility model:
[0051] During normal operation, the hook boom 5 is in a vertically raised position, and the hook boom 2 achieves the hooking and traction scheduling operation of railway trains through pitching and tilting movements.
[0052] When only the last car remains to be unloaded from the entire train, the hook boom 2 is raised to a vertical position, and the hook boom 5 is lowered to a horizontal position to hook with the last open car, thus pushing the train to complete the dispatching operation.
[0053] Furthermore, the shunting mechanism of this utility model is equipped with two shunting arms: one is a tilting and hooking arm used for traction and dispatching the entire train, and the other is a hooking and shunting arm used for pushing the last open wagon. The two shunting arms work together so that when only the last wagon remains to be unloaded from the entire train, the hooking arm at the rear can be used to push the train to complete the dispatching operation.
[0054] The innovation of this invention lies in providing a multifunctional double-arm shunting machine. Both arms of the shunting machine employ a pitching motion, replacing the telescopic arms of existing technologies with a simpler and more efficient pitching arm, thus enabling the coupling and traction of open wagons without disassembling them. A hooking arm and a hooking arm are respectively installed on the same side of the wagon body at the rear and front ends of the shunting machine. When only the last wagon remains to be unloaded, the hooking arm is raised to a vertical position, and the hooking arm is lowered to a horizontal position to hook with the last open wagon, thus pushing the railway train to complete the shunting operation. In this invention, by limiting the size and hinge point position of the pitching hooking arm, interference with railway open wagon accessories is prevented during the pitching process, solving the problem in existing technologies where interference with railway open wagon accessories prevents coupling operations.
[0055] After implementation, this utility model can be applied to tippler projects on the Daqin Railway or other ports at home and abroad. It can greatly reduce the weight of the car shifter in tippler systems without unloading operations, reduce the cost of the car shifter, and increase the gross profit margin of the tippler system.
[0056] Existing wagon towing machines with tilting booms can only perform hooking operations for general open wagons that are towed and unloaded. However, hooking operations for specialized open wagons that are not to be unloaded can only be achieved using telescopic booms. All double-boom wagon towing machines lack a tilting hooking boom. In contrast, the wagon towing machine of this invention is equipped with a tilting hooking boom, which can be used for hooking and towing operations of open wagons that are not to be unloaded.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
