Description

Technical Field

[0001] This utility model relates to the field of engine maintenance technology, specifically a lifting device structure for engine maintenance. Background Technology

[0002] Automotive repair is the process of diagnosing and repairing malfunctioning vehicles using professional technical means, with the aim of restoring the vehicle's normal performance and safety. Automotive repair is mainly divided into two categories: major repairs and minor repairs. Major repairs refer to restoring a vehicle's technical condition and extending its lifespan by replacing or repairing its parts. Minor repairs refer to routine maintenance and partial repairs.

[0003] Engine failure is a common problem in automotive repair, especially when repairing or replacing engine-related parts, which often requires removing the engine from the vehicle body. To facilitate this operation, an engine lift is typically used to hoist the engine. Existing engine lifting equipment uses a fixed bottom support structure, which makes moving the equipment very difficult. These lifting equipment are usually large and heavy, and the fixed bottom support cannot be effectively retracted or folded, resulting in significant manpower and time being required to move the lifting equipment from one repair location to another. Utility Model Content

[0004] The purpose of this invention is to provide a lifting device structure for engine maintenance, addressing the problem mentioned in the background section that existing engine maintenance lifting devices use a fixed bottom support frame design. Because the bottom support frame is fixed, moving these devices presents significant difficulties. These devices are typically large and heavy, and the fixed bottom support frame cannot be effectively retracted or folded, resulting in a significant amount of manpower and time being required to move the lifting device from one maintenance location to another.

[0005] To solve the above problems, this utility model provides the following technical solution: a lifting device structure for engine maintenance, comprising a base frame, a folding support section, and a suspension section:

[0006] The base frame has a connecting frame on its side, and a folding support part is located on the side of the base frame. The folding support part has a support rod a rotatably disposed within the connecting frame, and a support rod b rotatably disposed within the connecting frame. The support rod a and support rod b are arranged side by side and are engaged with each other. The rotation of the support rod a drives the support rod b to rotate and displace simultaneously. A control component is located at the top of the support rod a and support rod b to control their rotation angle. The suspension part is located at the top of the base frame and has a support frame located at the top of the base frame. A lifting arm for lifting is rotatably disposed at the top of the support frame.

[0007] By adopting the above technical solution, the support range can be adjusted by utilizing the rotational displacement of support rods a and b of the folding support part during engine maintenance, thereby enhancing the overall stability of the lifting device. At the same time, the boom of the suspension part can rotate, making it easy to adjust the lifting position and perform lifting operations on the engine, thus improving the convenience and efficiency of maintenance work.

[0008] Preferably, the suspension unit also has a telescopic arm that is slidably disposed inside the boom, with a hook provided at the outward end of the telescopic arm, and a hydraulic telescopic rod rotatably disposed at the bottom of the boom, with the end of the hydraulic telescopic rod away from the boom being rotatably connected to the support frame.

[0009] By adopting the above technical solution, the angle of the boom can be changed by controlling the extension and retraction of the hydraulic telescopic rod. At the same time, the telescopic boom can slide inside the boom, further adjusting the position of the hook and the lifting radius, which can more flexibly adapt to the engine lifting needs at different positions and heights.

[0010] Preferably, the bottom of the connecting frame is provided with casters, and the bottoms of the support rods a and b are also provided with casters.

[0011] By adopting the above technical solution, the overall movement and steering of the lifting device can be facilitated. At the engine maintenance site, the lifting device can be easily moved to the position where the engine needs to be lifted. At the same time, when the support rods a and b of the folding support part are rotated to unfold or retract, the universal wheels at the bottom can assist in its smooth movement and position adjustment, improving the convenience of operation.

[0012] Preferably, the folding support part also has a rotating shaft a disposed at one end of the support rod a, the rotating shaft a being embedded in the connecting frame and rotatably connected to the connecting frame, and a rotating shaft b disposed at one end of the support rod b, the rotating shaft b being embedded in the connecting frame and rotatably connected to the connecting frame.

[0013] By adopting the above technical solution, it can be ensured that support rod a and support rod b can rotate stably within the connecting frame with rotation axis a and rotation axis b as the center.

[0014] Preferably, the folding support part also has a transmission tooth a disposed at one end of the support rod a, and a transmission tooth b disposed at one end of the support rod b, and the transmission tooth a and the transmission tooth b are meshed together.

[0015] By adopting the above technical solution, when the support rod a rotates, the rotational force can be transmitted to the support rod b through the meshing of the transmission gear a and the transmission gear b, so as to realize the synchronous rotational displacement of the support rod a and the support rod b, and ensure that the two support rods of the folding support part can work together.

[0016] Preferably, the folding support also has a rotating groove a on the top of the support rod a, in which a rotating frame a is rotatably embedded; and a rotating groove b is provided on the top of the support rod b, in which a rotating frame b is rotatably embedded.

[0017] By adopting the above technical solution, rotating frame a can rotate within rotating groove a, and rotating frame b can rotate within rotating groove b, providing an adjustable structural basis for subsequent control of the rotation angles of support rod a and support rod b.

[0018] Preferably, the folding support also has a threaded rod rotatably disposed at one end of the rotating frame a, the threaded rod passing laterally through the rotating frame b and being nested and threadedly connected to the rotating frame b.

[0019] By adopting the above technical solution, the rotating frame b can be moved along the threaded rod by rotating the threaded rod and using its nested threaded connection with the rotating frame b. This causes the support rod b to rotate relative to the support rod a, thereby precisely controlling the rotation angle of the support rod a and the support rod b, and thus adjusting the support range and stability of the folding support part.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by providing a folding support part, the support range can be adjusted by utilizing the rotational displacement of support rods a and b of the folding support part during engine maintenance, thereby enhancing the overall stability of the lifting device. At the same time, the boom of the suspension part can rotate, making it easy to adjust the lifting position and perform lifting operations on the engine, thus improving the convenience and efficiency of maintenance work.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a lifting device structure for engine maintenance, including a base frame 1, a folding support part 2, and a suspension part 3.

[0031] A connecting frame 101 is provided on the side of the base frame 1, and a folding support part 2 is provided on the side of the base frame 1. The folding support part 2 has a support rod a201 rotatably disposed within the connecting frame 101, and a support rod b205 rotatably disposed inside the connecting frame 101. The support rod a201 and the support rod b205 are arranged side by side and are engaged with each other. The rotation of the support rod a201 drives the support rod b205 to rotate and move simultaneously. A control component is provided on the top of the support rod a201 and the support rod b205 to control the support rod a201. The rotation angle of support rod a205 and support rod b205 is such that the suspension part 3 is set on the top of the base frame 1. The suspension part 3 has a support frame 301 set on the top of the base frame 1. The top of the support frame 301 is rotatably equipped with a lifting arm 302 for lifting. During engine maintenance, the support range can be adjusted by utilizing the rotational displacement of support rod a201 and support rod b205 of the folding support part 2, thereby enhancing the overall stability of the lifting device. At the same time, the lifting arm 302 of the suspension part 3 can rotate, which facilitates the adjustment of the lifting position and the lifting operation of the engine, improving the convenience and efficiency of maintenance work.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a lifting device structure for engine maintenance, including a base frame 1, a folding support part 2, and a suspension part 3.

[0034] A telescopic boom 303 is slidably installed inside the boom 302. A hook 304 is provided at the outward end of the telescopic boom 303. A hydraulic telescopic rod 305 is rotatably installed at the bottom of the boom 302. The end of the hydraulic telescopic rod 305 away from the boom 302 is rotatably connected to the support frame 301. The angle of the boom 302 can be changed by controlling the extension and retraction of the hydraulic telescopic rod 305. At the same time, the telescopic boom 303 can slide inside the boom 302 to further adjust the position of the hook 304 and the lifting radius, which can more flexibly adapt to the engine lifting needs of different positions and heights.

[0035] The bottom of the connecting frame 101 is equipped with casters, and the bottoms of the support rods a201 and b205 are also equipped with casters, which facilitates the movement and turning of the entire lifting device. At the engine maintenance site, the lifting device can be easily moved to the position where the engine needs to be lifted. At the same time, when the support rods a201 and b205 of the folding support part 2 are rotated to unfold or fold up, the casters at the bottom can assist in their smooth movement and position adjustment, improving the convenience of operation.

[0036] A rotating shaft a202 is provided at one end of the support rod a201. The rotating shaft a202 is embedded in the connecting frame 101 and rotatably connected to the connecting frame 101. A rotating shaft b206 is provided at one end of the support rod b205. The rotating shaft b206 is embedded in the connecting frame 101 and rotatably connected to the connecting frame 101. This ensures that the support rods a201 and b205 can rotate stably within the connecting frame 101 with the rotating shafts a202 and b206 as the center.

[0037] A transmission tooth a203 is provided at one end of the support rod a201, and a transmission tooth b207 is provided at one end of the support rod b205. The transmission tooth a203 and the transmission tooth b207 mesh with each other, so that when the support rod a201 rotates, the rotational force is transmitted to the support rod b205 through the meshing of the transmission tooth a203 and the transmission tooth b207, so as to realize the synchronous rotational displacement of the support rod a201 and the support rod b205 and ensure that the two support rods of the folding support part 2 can work together.

[0038] A rotating groove a204 is provided at the top of the support rod a201, and a rotating frame a209 is rotatably embedded in the rotating groove a204. A rotating groove b208 is provided at the top of the support rod b205, and a rotating frame b210 is rotatably embedded in the rotating groove b208. The rotating frame a209 can rotate in the rotating groove a204, and the rotating frame b210 can rotate in the rotating groove b208, providing an adjustable structural basis for subsequent control of the rotation angle of the support rod a201 and the support rod b205.

[0039] A threaded rod 211 is rotatably provided at one end of the rotating frame a209. The threaded rod 211 passes laterally through the rotating frame b210 and is nested and threadedly connected to the rotating frame b210. By rotating the threaded rod 211, the rotating frame b210 can be moved along the threaded rod 211, thereby driving the support rod b205 to rotate relative to the support rod a201. The rotation angle of the support rod a201 and the support rod b205 can be precisely controlled, thereby adjusting the support range and stability of the folding support part 2.

[0040] Working principle: First, using the casters at the bottom of the side connecting frame 101 of the base frame 1 and the casters at the bottom of the support rods a201 and b205 of the folding support part 2, the entire lifting device is easily moved to the position where the engine needs to be lifted at the engine repair site. Then, the control component of the folding support part 2, namely the rotating threaded rod 211, is operated. Since the threaded rod 211 is nested and threadedly connected to the rotating frame b210, when the threaded rod 211 is rotated, the rotating frame b210 will move along the threaded rod 211. And because the rotating frame a201... Rotary support a209 is rotatably embedded in the rotating groove a204 at the top of support rod a201, and rotating frame b210 is rotatably embedded in the rotating groove b208 at the top of support rod b205. Therefore, the movement of rotating frame b210 will cause support rod b205 to rotate relative to support rod a201. At the same time, the transmission gear a203 at one end of support rod a201 meshes with the transmission gear b207 at one end of support rod b205, and support rod a201 will also rotate accordingly. The two rotate synchronously, thereby achieving precise control of support rod a201. The rotation angle of support rod b205 and 01 is adjusted to improve the support range of folding support 2 and enhance the overall stability of the lifting device. Next, suspension 3 is adjusted to accommodate the engine's lifting position. The extension and retraction of hydraulic telescopic rod 305 is controlled. Since one end of hydraulic telescopic rod 305 is rotatably connected to the bottom of boom 302 and the other end is rotatably connected to support frame 301, the extension and retraction of hydraulic telescopic rod 305 changes the angle of boom 302. Simultaneously, telescopic arm 303 can slide within boom 302, further adjusting the outward direction of telescopic arm 303. The position and lifting radius of the end hook 304 are adjusted so that the hook 304 accurately reaches the lifting point of the engine. Finally, the hook 304 is connected to the engine, and the lifting operation is carried out using the boom 302 of the suspension part 3 to inspect the engine. If it is necessary to change the lifting position during the inspection, the angle of the boom 302, the position of the telescopic boom 303, and the support range of the folding support part 2 can be adjusted again to meet different inspection needs. After the inspection is completed, the lifting equipment is retracted and moved to a suitable storage location in reverse order.
