Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, specifically to a transfer device for power facilities and equipment. Background Technology

[0002] Electrical equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, instrument transformers, contactors, etc. A transfer device is required when installing electrical equipment.

[0003] For power transfer vehicles, the movement of the vehicle requires a lead vehicle to pull it. During the movement of the vehicle, if the lead vehicle turns, the vehicle needs a large turning space to complete the turn. If the turn is too sharp, the front wheels of the vehicle may deviate, causing the vehicle to overturn. At the same time, the vehicle does not have automatic braking during the transfer process, which is very dangerous when transferring power equipment. Therefore, it is urgent to design a power facility and equipment transfer device to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a power facility and equipment transfer device, which has the function of turning the front wheels with the direction of rotation of the traction rod. When the transfer vehicle needs to turn, the front wheels will automatically turn with the rotation of the traction rod, allowing the transfer vehicle to quickly complete the turn without requiring a large turning space, making it more convenient to use. At the same time, it is equipped with a rear brake that is connected to the traction frame, which can automatically brake the transfer vehicle to a stop when the vehicle in front stops, ensuring the safety of the transfer vehicle during use.

[0005] This utility model provides a power facility and equipment transfer device:

[0006] The system includes a transfer platform, with symmetrical differential rear wheels fixed on both sides of the bottom rear of the transfer platform. A symmetrical follow-rotating front wheel is provided on the bottom side of the transfer platform away from the differential rear wheels. A traction rod is provided between the follow-rotating front wheels in front of the bottom of the transfer platform.

A rear brake is provided on the side of the differential rear wheel near the follow-rotating front wheel. The rear brake is connected to the steering wheel in a transmission connection.

[0007] Preferably, two sets of symmetrical bolt rings are fixed around the top surface of the transfer platform. One end of each bolt ring is threaded onto the inner side of the transfer platform. A front wheel lever is provided on the bottom surface of the transfer platform at the position where the front wheel follows the rotation. The front wheel follows the rotation and is hinged to the bottom of both ends of the front wheel lever. Symmetrical limited-slip brackets are fixed on both sides of the transfer platform at the position where the front wheel lever connects to the front wheel lever. The front wheel lever slides horizontally inside the limited-slip bracket. A vertical limited-slip rod is fixed on the bottom surface of the position where the front wheel lever connects to the limited-slip bracket. A limiting groove is provided at the center of the bottom surface of the limited-slip bracket. The vertical limited-slip rod slides inside the limiting groove. A steering center rod is vertically fixed at the center of the bottom surface of the front wheel lever. The steering wheel is limited and rotates outside the steering center rod.

[0008] The bolt rings on the top of the transfer platform can be used to reinforce the electrical equipment. The bolt rings themselves are threaded to the transfer platform and can be removed when not in use. The design of the front wheel lever and the limited-slip bracket makes the transfer platform a driven structure that moves with the position of the front wheel. It can move back and forth with the pulling and pushing of the traction rod, and the transmission bar connected to the end of the front wheel lever can be used to push the rear brake. The limiter at the bottom of the limited-slip bracket is connected to the front grass and the vertical limited-slip rod, which can limit the front wheel lever and prevent it from sliding to the sides, ensuring the sliding direction of the front wheel lever.

[0009] Preferably, a fixed wheel frame is fixed at the position where the transfer platform connects to the differential rear wheel, and the differential rear wheel is rotatably connected to the side of the fixed wheel frame. The fixed wheel frame at the position of the differential rear wheel can complete the connection and fixation between the differential rear wheel and the transfer platform.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see the appendix Figures 1-4 This utility model provides a power facility and equipment transfer device, which includes:

[0025] The transfer platform 1 has symmetrical bolt rings 11 threaded around its top surface. The bolt rings 11 facilitate the binding of the electrical equipment being transferred on the transfer platform 1, improving the safety of the transfer. When not in use, the bolt rings 11 can be removed due to the threaded connection.

[0026] A front wheel lever 12 is provided on the bottom surface of the front of the transfer platform 1. The front wheel lever 12 is slidably connected to the bottom surface of the transfer platform 1. Symmetrical limited-slip brackets 121 are fixed on both sides of the position where the front wheel lever 12 is connected to the bottom surface of the transfer platform 1. A vertical limiting groove 123 is opened in the middle of the bottom surface of the limited-slip bracket 121. The front wheel lever 12 is limited to slide inside the limited-slip bracket 121. A vertical limited-slip rod 122 is fixed on the bottom surface where the front wheel lever 12 is connected to the limited-slip bracket 121. The vertical limited-slip rod 122 slides inside the limiting groove 123. Through the design of the vertical limited-slip rod 122, the front wheel lever 12 can slide in a specified direction without sliding diagonally or laterally.

[0027] A steering center rod 124 is vertically fixed at the center of the bottom surface of the front wheel slab 12. A steering wheel 5 with a rotation function is fitted on the outer side of the steering center rod 124. A transmission bar 125 that slides against the bottom surface of the transfer platform 1 is vertically fixed at the position where the front wheel slab 12 connects to the steering center rod 124. The other end of the transmission bar 125 extends to the rear of the transfer platform 1. A limit seat 127 is fixed at the position where the transmission bar 125 is connected to the rear of the transfer platform 1. The limit seat 127 can limit the transmission bar 125, so that the limit bar always slides in a horizontal direction. A transverse push rod 126 is vertically connected to the end of the transmission bar 125 outside the limit seat 127. The transverse push rod 126 can transmit the power of the transmission bar 125 to both sides of the transfer sleeve.

[0028] A symmetrical fixed wheel frame 21 is fixed on the bottom surface of the transfer platform 1 at the position behind the transverse push rod 126. A differential rear wheel 2 is rotatably connected to the side of the fixed wheel frame 21. The fixed wheel frame 21 can stably connect the differential rear wheel 2 to the bottom surface of the transfer platform 1. The setting of the differential rear wheel 2 allows the two wheels at the rear of the transfer platform 1 to rotate at different speeds, ensuring the stability of the transfer platform 1 when turning.

[0029] At the bottom front of the transfer platform 1, symmetrical L-shaped bogies 31 are hinged to the bottom surfaces of both ends of the front wheel sprocket 12. The design of the L-shaped bogies 31 allows the following front wheels 3 connected to the bottom side of the L-shape to have the function of rotation. A steering transmission rod 32 is fixed horizontally in the middle of the side of the L-shaped bogie 31 away from the following front wheels 3. The end of the steering transmission rod 32 away from the L-shaped bogie 31 is hinged to the steering transmission rod 32, and the other end of the steering transmission rod 32 is hinged to the bottom surface of the steering wheel 5. The end of the steering transmission rod 32 that is hinged to the steering wheel 5 is located at the end of the steering wheel 5 away from the front wheel sprocket. This connection method allows the steering wheel to have sufficient thrust or pull force during rotation, and at the same time drive the two following front wheels to rotate, thus completing the steering.

[0030] A traction rod 4 is horizontally fixed on one side of the steering wheel 5 in front of the transfer platform 1. The traction rod 4 facilitates the connection between the transfer platform 1 and the tractor. The front end of the traction rod 4 is provided with a traction assembly head 41, which allows the traction rod 4 to quickly complete the traction connection with the tractor.

[0031] A symmetrical rear brake 6 is fixed near the differential rear wheel 2 on the lateral push rod 126. A brake pad 61 is embedded in the rear brake 6 at the position where it contacts the differential rear wheel 2. The brake pad 61 contacts the differential rear wheel 2. Through the design of the rear brake 6, when the transfer vehicle stops, the front wheel lever 12 is pushed by the traction rod 4 to move the rear brake 6 backward, so that the brake pad 61 contacts the differential rear wheel 2, realizing the function of deceleration of the transfer platform 1, thereby reducing the forward inertial force of the transfer vehicle when it stops and improving the safety of the transfer vehicle during use.

[0032] Usage process:

[0033] Connect the traction assembly head 41 at the front end of the traction rod 4 to the tractor vehicle. Then, place the power equipment to be transferred on the upper part of the transfer platform 1 and fix the power equipment with the bolt ring 11. Start the transfer vehicle to complete the movement of the transfer platform 1 and complete the transfer of the power equipment.

[0034] During the transfer process, if a turn is required, the tow bar 4 will drive the steering wheel 5 to rotate when the transfer vehicle turns, completing the steering of the front wheel 3 at the bottom of the transfer platform 1, allowing the transfer vehicle to complete the turn in a safe and stable manner. When the transfer vehicle stops, the tow bar 4 receives the inertial thrust of the transfer platform 1, which will cause the rear brake 6 to engage with the differential rear wheel 2, thereby achieving the purpose of decelerating the transfer vehicle, reducing the thrust of the transfer vehicle when it stops, and improving the safety of the transfer vehicle during the transfer of power equipment.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
