Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically to a portable equipment support lifting bracket. Background Technology

[0002] Field projects involve a large workload, fast operation, and frequent relocation. To save costs to the greatest extent, temporary storage of equipment is an important task after a project is completed, especially when new projects are not yet confirmed. In order to better achieve the project's goal of "safe" and rapid repair, while ensuring project production, it is necessary to strengthen the protection of temporary equipment storage and reduce transportation costs, and keep up with the rapid pace of project production. This requires innovation in equipment support work to reduce maintenance costs and safety hazards during use.

[0003] During the project's operational phase, temporary equipment storage locations were often in poor condition, frequently being open-air plazas. Wind, sand, and direct sunlight caused significant wear and tear on the vehicles, especially prolonged periods of stationary parking, which severely damaged tires and rims. Years of construction in the desert led to equipment aging and frequent inflation and deflation. When parked, severely deflated tires could not be properly supported, causing serious damage and even deformation to the rims and tires. This increased maintenance costs for subsequent construction and even posed a significant safety hazard if tires or rims came off during operation.

[0004] In the prior art, patent document CN102241375A discloses a screw lifting mechanism and an automatic lifting platform. This technical solution uses a lifting nut to raise and lower the screw, thereby lifting the equipment. However, this solution requires a seat cover to be fixedly mounted on a bracket, which lacks portability and is inconvenient for direct application in lifting vehicle chassis stored outdoors. Therefore, the technical solution needs optimization and improvement. When the vehicle chassis is lifted, existing support equipment improves stability by increasing the support surface. While this improves stability after the chassis is lifted, it increases the overall size, contradicting the requirement for portability. Therefore, it is necessary to improve stability while still meeting portability requirements. Utility Model Content

[0005] The main purpose of this utility model is to provide a lifting bracket that is convenient to carry, transport and store, and can effectively improve stability after lifting the vehicle chassis.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: The portable device supports a lifting bracket, including a base plate. A support cylinder is concentrically fixed at the upper end of the base plate. A threaded sleeve is concentrically rotatably installed at the upper end of the support cylinder. A first screw passes through the threaded sleeve and is threadedly connected to the threaded sleeve. A second screw is concentrically threaded to the upper part of the first screw, with the upper end of the second screw located above the first screw. Vertical grooves are provided on both the front and rear sides of the support cylinder, and sliding plates are slidably installed in each groove. The sliding plates pass through one of the vertical grooves. A vertical chisel is fixed to the lower end of the sliding plate on the outer side of the support cylinder. A through hole concentric with the chisel is provided on the base plate. A vertical upper rack is fixed to one end of the sliding plate inside the support cylinder. A gear that meshes with the upper rack is rotatably installed inside the support cylinder. An outer sleeve is fixed to the lower end of the first screw inside the support cylinder. Vertical lower racks are fixed to both the front and rear ends of the outer sleeve and mesh with the gear on one side.

[0007] Specifically, a fixed base is concentrically fixed at the upper end of the support cylinder, and the fixed base and the threaded sleeve are rotatably connected through an end face bearing.

[0008] Specifically, a top plate is fixed to the upper end of the second screw.

[0009] Specifically, the left and right ends of the outer sleeve are fixed with sliding rods, and the inner wall of the support cylinder is provided with sliding grooves corresponding to the sliding rods, and the sliding rods are slidably disposed in the sliding grooves.

[0010] Specifically, multiple handles are evenly distributed and fixed around the outer circumference of the threaded sleeve.

[0011] Specifically, the two drill rods are symmetrically arranged front and back according to the axis of the support cylinder. The base is located above the square timber. After the drill rod passes through the hole, the outer edge of the drill rod contacts the side wall of the square timber on one side.

[0012] Specifically, the lower end of the drill rod is a pointed tip.

[0013] Specifically, the fixed seat and the base plate are fixedly connected by multiple tie rods, which are evenly distributed around the circumference of the support cylinder.

[0014] Specifically, the fixed base is threaded with a locking screw, which can be tightly pressed against the threaded sleeve after being rotated.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the chisel mechanism (slide plate, upper rack, gear and lower rack linkage), the chisel automatically inserts into the ground when lifting the vehicle chassis, providing additional anchoring force to prevent the equipment from shifting or tipping over, and ensuring the overall stability and reliability of the lifting process.

[0016] 2. The design of the second screw allows for adjustment of the distance between the top plate and the vehicle chassis, thereby flexibly controlling the upward stroke of the first screw and the downward depth of the chisel, ensuring that the chisel can always be inserted into the ground to the appropriate length, adapting to different chassis height requirements, and improving operational accuracy.

[0017] 3. Lifting the vehicle chassis reduces or eliminates tire pressure, preventing tire deformation or damage due to long-term load, effectively extending the service life of vehicle tires and reducing maintenance costs.

[0018] 4. Add square timber under the base plate to isolate the base plate from the damp ground, prevent the base plate from rusting, and increase the support area to improve the durability and overall stability of the equipment in humid areas.

[0019] 5. The handle design on the outer edge of the screw sleeve facilitates manual rotation or installation of the force-adding sleeve; the tie rod strengthens the support structure; the automatic reset mechanism during dismantling (the drill rod automatically exits the ground as the first screw descends) simplifies the operation process, reduces manual intervention, and improves equipment life and reliability.

[0020] 6. The sliding connection between the slide rod and the slide groove can straighten the lower end of the first screw, improving the stability of the first screw during its up-and-down movement.

[0021] 7. The upper rack, lower rack and gear mesh, the outer sleeve is fixedly connected to the lower end of the first screw, the upper rack is fixedly connected to the slide plate, and the slide plate is slidably set in the vertical groove. Therefore, during the rotation of the screw sleeve, when the first screw, the second screw and the top plate are moving upward without load, the first screw cannot rotate with the screw sleeve, which facilitates the lifting operation of the vehicle chassis.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] The portable device supports a lifting bracket, including a base plate 1. A support cylinder 2 is concentrically fixed to the upper end of the base plate 1, and a threaded sleeve 4 is concentrically rotatably mounted on the upper end of the support cylinder 2. Specifically, a fixing seat 3 is concentrically fixed to the upper end of the support cylinder 2, and the fixing seat 3 and the threaded sleeve 4 are rotatably connected by an end face bearing 18. Multiple handles 5 are evenly distributed around the outer circumference of the threaded sleeve 4. The fixing seat 3 and the base plate 1 are fixedly connected by multiple tie rods 21, which are evenly distributed around the circumference of the support cylinder 2.

[0033] The fixed base 3 is threaded with a locking screw. After rotating the locking screw, the locking screw can press against the screw sleeve 4, thereby locking the screw sleeve 4.

[0034] Multiple tie rods 21 can improve the structural strength of this lifting support. The handle 5 facilitates the rotation of the screw sleeve 4 and the installation of the force-applying sleeve.

[0035] The first screw 6 passes through the screw sleeve 4 and is threadedly connected to the screw sleeve 4. The upper part of the first screw 6 is concentrically threaded with a second screw 7. The upper end of the second screw 7 is located above the first screw 6, and a top plate 8 is fixed to the upper end of the second screw 7.

[0036] Vertical grooves 11 are provided on both the front and rear sides of the support cylinder 2. Slide plates 9 are slidably installed in the vertical grooves 11, and the slide plates 9 pass through the vertical grooves 11 on one side.

[0037] A vertical chisel 10 is fixed to the lower end of the slide plate 9 on the outside of the support cylinder 2. The lower end of the chisel 10 is pointed. A through hole 13 concentric with the chisel 10 is opened on the bottom plate 1. A vertical upper toothed rack 14 is fixed to one end of the slide plate 9 inside the support cylinder 2.

[0038] The support cylinder 2 is rotatably equipped with a gear 15 that meshes with the upper rack 14. The lower end of the first screw 6 inside the support cylinder 2 is fixed with an outer sleeve 17. Both the front and rear ends of the outer sleeve 17 are fixed with vertical lower racks 16, which mesh with the gear 15 on one side.

[0039] Both ends of the outer sleeve 17 are fixed with sliding rods 19, and the inner wall of the support cylinder 2 is provided with a sliding groove 20 corresponding to the sliding rod 19. The sliding rod 19 is slidably disposed in the sliding groove 20. The sliding connection between the sliding rod 19 and the sliding groove 20 can straighten the lower end of the first screw 6, thereby improving the stability of the first screw 6 during its up and down movement.

[0040] The upper rack 14, lower rack 16 and gear 15 mesh together. The outer sleeve 17 is fixedly connected to the lower end of the first screw 6. The upper rack 14 is fixedly connected to the slide plate 9. The slide plate 9 is slidably set in the vertical groove 11. Therefore, when the screw sleeve 4 rotates, the first screw 6 cannot rotate with the screw sleeve 4 when the first screw 6, the second screw 7 and the top plate 8 are moving upward without load, which facilitates the lifting operation of the vehicle chassis.

[0041] When using this device, the base plate 1 is brought into contact with the ground, the second screw 7 is rotated, and the distance between the top plate 8 and the vehicle chassis is adjusted to ensure that the first screw 6 can lift the vehicle chassis during its effective upward rotation stroke.

[0042] Then, by rotating the screw sleeve 4, the outer sleeve 17, slide rod 19, first screw 6, second screw 7, lower rack 16, and top plate 8 move upwards. During the upward movement of the lower rack 16, gear 15 rotates. As gear 15 rotates, the upper rack 14, slide plate 9, and chisel 10 move downwards. During this downward movement, chisel 10 can penetrate below the ground. As the top plate 8 contacts the vehicle chassis and lifts the chassis, chisel 10 continues to move downwards and penetrates deep below the ground. By setting chisel 10, which automatically inserts below the ground, additional anchoring force is provided to prevent the lifting bracket from shifting or tipping over, ensuring the overall stability and reliability of the lifting process.

[0043] When the lifting bracket is dismantled, the lower rack 16 moves downward during the downward movement of the first screw 6. The lower rack 16 causes the upper rack 14 to move upward through the gear 15. During the upward movement of the upper rack 14, the chisel 10 moves upward. After the first screw 6 is reset, the chisel 10 is withdrawn from below the ground and reset.

[0044] In this technical solution, since the distance between the top plate 8 and the vehicle chassis can be adjusted by the second screw 7, the upward stroke of the first screw 6 when the vehicle chassis is lifted into place can be adjusted, thereby adjusting the downward stroke of the drill rod 10 to ensure the length of the drill rod 10 inserted below the ground, thus ensuring the stability of the lifting bracket after the vehicle chassis is lifted.

[0045] After this lifting bracket lifts the vehicle chassis, the pressure on the tires is reduced or eliminated, which can improve the service life of the vehicle tires.

[0046] Example 2: Based on Example 1, referring to... Figure 3 and Figure 8As shown, the two drill rods 10 are symmetrically arranged front and back according to the axis of the support cylinder 2. The base is located above the square timber 12. After the drill rod 10 passes through the through hole 13, the outer edge of the drill rod 10 contacts the side wall of the square timber 12 on one side.

[0047] In some humid areas, by setting square timber 12 under the base plate 1, the base plate 1 can be separated from the ground, which can prevent the base plate 1 from rusting and also increase the support area.

[0048] In this embodiment, by controlling the distance between the two chisels 10, the outer edge of the chisel 10 after passing through the through hole 13 contacts the side wall of the square timber 12 on one side, which can restrict the square timber 12 to be centered below the base plate 1, thereby enabling the lifting bracket to maintain sufficient stability after lifting the vehicle chassis.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
