The working principle of the utility model is as follows:
in the process of using the crane for rail maintenance operation, when the operation is required to be carried out by parking, parking and braking parking can be realized without applying force to the transverse push rod 501. Naturally, when parking is required, the worker stops pushing the crane, i.e. stops applying force to the transverse pushing rod 501, so that the parking is realized without extra redundant operation or attention to the parking operation. Specifically, when the lateral push rod 501 is not pushed, the second push rod 504 does not apply a force to the higher end of the first push rod 404 (i.e., the higher end of the first push rod 404 is pushed downward); at this time, in the parking assembly 4, under the action of the pushing and extending of the return spring 405, the brake pad 406 is pressed down, so that the brake pad 406 contacts with the rolling surface of the roller 2, and thus the roller 2 cannot roll under the action of the friction force of the brake pad 406, thereby realizing automatic parking; when lifting operation is needed after parking, and the weight of the lifted object is light, the positioning assembly 7 can be not used for positioning the crane; if the volume and the weight of the lifted object are large, the crane needs to be stably fixed on the track by utilizing the positioning assembly 7 so as to prevent the crane from turning on one's side; specifically, when the positioning assembly 7 is used for positioning, the positioning sleeve 702, the positioning inserting rod 703 and the bolt 705 are matched to adjust the inserting height of the inserting rod 703, so that the I-steel clamp 704 can clamp the track to achieve the purpose of fixing the crane;
in the process of using the crane for rail maintenance operation, when the crane needs to be moved, the transverse pushing rod 501 is forced (if the I-steel clamp 704 is fixed with the rail, the I-steel clamp 704 should be detached from the rail first). Of course, when the vehicle needs to be moved, a worker needs to push the transverse push rod 501, namely, apply force to the transverse push rod 501, so that the vehicle can be moved without unnecessary operation of releasing the parking state; specifically, when pushing the transverse pushing rod 501, since the upper end of the vertical pushing rod 502 is connected with the end of the transverse pushing rod 501, the lower end of the vertical pushing rod 502 is hinged with the guardrail 3, and the lower end of the vertical pushing rod 502 is connected with the second pressing rod 504, so that the transverse pushing rod 501 drives the vertical pushing rod 502 to rotate around the hinged end thereof, and the second pressing rod 504 is further rotated to press the higher end of the first pressing rod 404; one end of the parking plate 403 is connected with the upper end of the parking connecting rod 402, while the other end is connected with the lower end of the first pressing rod 404, so that the lower end of the first pressing rod 404 drives the connecting end of the parking plate 403 and the parking connecting rod 402 to lift up after being pressed down, and further the parking connecting rod 402 slightly lifts up, and further drives the brake block 406 to lift up, so that the brake block 406 is separated from the rolling surface of the roller 2, the roller 2 can roll freely, at the moment, under the condition of applying force to the transverse pushing rod 501, the parking state of the crane is released, and meanwhile, the crane is moved by virtue of the thrust from the transverse pushing rod 501;
according to the crane for rail maintenance operation, the parking assembly, the trolley assembly and the positioning assembly are arranged, and when the crane is used, the parking state of the crane can be relieved by pushing the transverse pushing rod, so that the crane body is pushed to slide to a designated position freely, and transportation operation is carried out; when the vehicle body is pushed to a designated position, the automatic parking can be realized without pushing the transverse push rod by loosening the hand, and the lifting operation or the feeding and discharging operation can be performed by parking, so that the accident caused by sliding the vehicle can be effectively prevented; when the hoisting operation is carried out, the crane is fixed on the track through the positioning assembly, so that the crane is prevented from turning on one's side in the hoisting process, and the construction safety is improved. In addition, when the utility model is used, the parking state is not required to be controlled deliberately and other operations are not required to be additionally added to change the parking state, so that the operation efficiency can be improved.
In order to facilitate pushing and holding the transverse pushing rod 501, further, in a preferred embodiment, referring to fig. 2 and 3, a rubber grip 5011 is coated on the surface of the transverse pushing rod 501.
In order to prevent the first lever 404 from swinging back and forth to disengage from the second lever, further, in a preferred embodiment, referring to fig. 1 to 4, the parking bracket 401 is provided with a lever stopper 407; the pressure lever limiting member 407 is vertically provided with a pressure lever limiting groove 4071 along the length direction thereof, and the first pressure lever 404 is arranged to penetrate through the pressure lever limiting groove 4071.
In order to increase the friction between the brake pad 406 and the roller 2 to improve the parking effect, further, in a preferred embodiment, referring to fig. 2, the brake pad 406 has an arc-shaped structure matching with the rolling surface of the roller 2.
Further, in a preferred embodiment, the lifting device 6 includes a base 601 disposed on the frame 1, a column 602 and a counterweight 603 disposed on the base 601, a boom 604 connected to the column 602, a hook 605 disposed at an end of the boom 604, a hydraulic system 606 for driving the boom 604 to extend and retract, and a power device 607 for providing power to the hydraulic system 606.
Further, in a preferred embodiment, the power plant 607 is a fuel engine.
In order to increase the service life of the roller, further, in a preferred embodiment, the roller 2 is a steel wheel.
