Description

Technical Field

[0001] The present application relates to the field of bridge construction, and in particular to a wet joint formwork hoisting motorized trolley. Background Art

[0002] The upper structure of the extended beam bridge mostly adopts the prefabricated assembly construction technology, that is, the beam body is prefabricated in blocks in the prefabrication yard in advance, and transported to the site for assembly. There are joints between the beam bodies of each block, and cast-in-place concrete is needed to cast the joints to connect the beam bodies into a whole. Such joints are called wet joints.

[0003] In the concrete pouring construction of wet joints, the construction of the formwork is an important operation process. The formwork needs to be lifted upward from the bottom of the bridge, and finally the formwork is at the bottom of the bridge and the joint is sealed. During the lifting, a lifting rope is lowered above the bridge, and the lifting rope passes through the joint and connects to the formwork. The formwork is dragged upward by the lifting rope. When the formwork reaches the bottom of the bridge, the formwork is fixed to complete the construction. In the current wet joint pouring construction, a hand-pushed trolley is used, on which a winch is installed. The winch is used to control the up and down retraction and release of the lifting rope. Multiple templates are arranged in sequence along the length direction of the joint, so the hand-pushed trolley is pushed by manpower, and it gradually moves along the length direction of the joint as the installation progresses.

[0004] According to the actual operation of the trolley, the best operating position for the operator to move the trolley is in the front or rear of the trolley's moving direction, and this position is just above the wet joint. When the width of the joint is large, the operator's walking safety and convenience will be greatly reduced. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The present application embodiment discloses a wet joint template hoisting motorized trolley, such as Figure 1 As shown, the frame 1 includes a motorized wheel 10, a winch 13 and a driving mechanism 2. The motorized wheel 10 is in contact with the ground and is responsible for moving the frame 1 relative to the ground. The winch 13 is used to retract and release the lifting rope to lift the template. The driving mechanism 2 is used for the operator to operate and control the operation of the motorized wheel 10, thereby controlling the frame 1 to move along the length direction of the joint.

[0022] like Figure 1 As shown, there are four motorized wheels 10, which are respectively located at the four corners of the frame 1. The driving mechanism 2 includes a driving seat assembly 22 and an operating device 21. The specific structure and operation mode of the operating device 21 and the four motorized wheels 10 are similar to those of electric locomotives. The operating device 21 can control the rotation and steering of the motorized wheels 10, as well as the braking and parking of the frame 1. A door-shaped mounting frame 12 is fixedly connected above the frame 1, and a winch 13 is arranged on the mounting frame 12; the driving seat assembly 22 provides a driving space for the operator, and the operating device 21, the driving seat assembly 22 and the mounting frame 12 are arranged in sequence along the length direction of the joint, that is, when the operator controls the operating device 21 on the driving seat assembly 22, the mounting frame 12 is located behind the operator, so the mounting frame 12 and the winch 13 will hardly affect the operator's field of vision when the operator is driving.

[0023] like Figure 1 As shown, an adjusting block 121 is slidably provided on the mounting frame 12, and the winch 13 is fixedly installed on the adjusting block 121. The sliding direction of the adjusting block 121 relative to the mounting frame 12 is horizontal and perpendicular to the length direction of the joint, and the adjusting block 121 is also provided with a motor for driving the adjusting block 121 to move. At this time, the mounting frame 12 is similar to a small gantry, so that the lifting rope on the winch 13 can be located just above the middle position of the joint.

[0024] like Figure 1As shown, the driver's seat assembly 22 includes an adjustment frame 223 and a seat cushion 221. The seat cushion 221 is located on the adjustment frame 223. The adjustment frame 223 slides relative to the vehicle frame 1, and the sliding direction is parallel to the length direction of the joint. The sliding of the adjustment frame 223 is used to adjust the distance between the seat cushion 221 and the operating device 21, so that the driver can maintain a relatively comfortable and convenient operating posture. The adjustment frame 223 is welded and assembled by a plurality of square steel tubes, and includes a supporting portion 2231 and a matching portion 2232 that are fixedly connected to each other. The length direction of the matching portion 2232 forms an obtuse angle with the length direction of the supporting portion 2231. The seat cushion 221 is located at one end of the supporting portion 2231 away from the matching portion 2232. The matching part 2232 has two square steel pipes, and two adjustment steel pipes 11 are fixedly connected to the frame 1. The length direction of the adjustment steel pipe 11 is parallel to the length direction of the joint. A single adjustment steel pipe 11 is used to insert a square steel pipe of the matching part 2232. When the length direction of the matching part 2232 is horizontal, the support part 2231 is tilted and bent upward relative to the matching part 2232; when the operator sits on the seat cushion 221, the adjustment frame 223 is a lever, and the connection point between the matching part 2232 and the support part 2231 is a fulcrum. Under the support of the inner wall of the adjustment steel pipe 11, the adjustment frame 223 maintains a stable state.

[0025] like Figure 1 and 2 As shown, a rotating shaft 222 is fixedly connected below the seat cushion 221, and the rotating shaft 222 is inserted into the adjustment frame 223 in the vertical direction. The seat cushion 221 is rotatably connected relative to the adjustment frame 223 through the rotating shaft 222, that is, the operator sits on the seat cushion 221, and by rotating the seat cushion 221, the operator can selectively adjust himself to face the operating device 21 or the winch 13. A stop pin 224 is slidably connected to the support portion 2231 of the adjustment frame 223, and the sliding direction is the horizontal direction and the radial direction of the rotating shaft 222. The stop pin 224 is located on one side of the rotating shaft 222, and a return spring 225 is also connected to the adjustment frame 223, one end of the return spring 225 is connected to the adjustment frame 223, and the other end is connected to the stop pin 224. The rotation shaft 222 is provided with a stop hole 2221 for inserting the stop pin 224. The stop hole 2221 passes through opposite sides of the rotation shaft 222. In a natural state, the return spring 225 always exerts a force on the stop pin 224 to move it close to the rotation shaft 222. The end of the stop pin 224 is inserted into the stop hole 2221, and the seat cushion 221 cannot rotate at this time. When the seat cushion 221 is at an angle facing the operating device 21 and the mounting frame 12, the stop hole 2221 can be inserted by the stop pin 224 and maintain a stable posture.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
