Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, specifically to an anti-skid engineering vehicle jack. Background Technology
[0002] In engineering construction and field operations, engineering vehicles (such as excavators, bulldozers, and dump trucks) often face extreme operating environments with complex terrain, soft ground, or slippery surfaces. Traditional jacks, as an important vehicle support and lifting device, are typically installed at the bottom of the vehicle for maintenance, tire replacement, or temporary support. However, most traditional jacks are designed for flat, hard ground. When encountering low-traction surfaces such as sand, mud, or snow, their bases are prone to sinking or slipping, causing the jacks to tilt, deform, or even become unstable, easily leading to accidents involving personal injury and equipment damage. Furthermore, due to the heavy weight and unique fulcrum distribution of some engineering vehicles, higher requirements are placed on the load-bearing stability and support angle of the jacks. Most existing jacks fail to balance lifting capacity with ground adhesion, thus failing to meet the safety support needs of engineering vehicles in various scenarios and environments.
[0003] Furthermore, while some portable or vehicle-specific jacks on the market attempt to add anti-slip pads or widen the ground contact area on the base, their structures remain primarily fixed, unable to automatically adjust the contact angle according to different terrains. This results in limited effectiveness on slopes or irregular surfaces. Additionally, if the jack fails to effectively distribute the vehicle's weight or does not maintain sufficient contact with the ground during use, it is highly susceptible to tipping and slippage. Existing technology also lacks engineering vehicle jack devices that integrate "terrain adaptability, anti-slip design, and anti-settlement capability." Therefore, developing a robust, adaptable engineering vehicle jack with excellent anti-slip properties is crucial for significantly improving construction safety and efficiency, and possesses promising market prospects and application value, thus requiring urgent technological innovation and structural optimization.
[0004] In view of the above, in order to overcome the above technical problems, this utility model designs an anti-skid engineering vehicle jack, which solves the above technical problems. Utility Model Content
[0005] The technical objective of this invention is to develop a robust, adaptable engineering vehicle jack with excellent anti-slip properties, thereby significantly improving construction safety and efficiency.
[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution:
[0007] An anti-slip engineering vehicle jack mainly comprises a fixed base, support rod, fixing block, adjusting shaft, drive end, lifting block, and anti-slip mechanism. The fixed base is located at the bottom of the entire device, serving as a support foundation to ensure stable ground contact during use. The support rod is vertically mounted above the fixed base to bear vertical loads from the vehicle and connects the upper and lower structures. A fixing block is connected to the upper end of the support rod, and two support rods are mounted on the fixing block to enhance structural stability and load-bearing capacity. An adjusting shaft passes between the two fixing blocks to adjust the jack's support height and angle. One end of the shaft is connected to the drive end, which can be equipped with a motor for automatic control or a manual crank for manual operation, improving the device's adaptability and flexibility. The lifting block is located at the top of the jack structure and is a key component that contacts the bottom of the vehicle and transmits lifting force. To ensure stable support even on wet, soft, or sloping surfaces, the jack is specially equipped with an anti-slip mechanism at the bottom of the fixed base. This mechanism increases friction with the ground and prevents slippage or sinking due to uneven force or poor ground conditions, thus improving the safety and reliability of the equipment in complex environments.
[0008] The anti-slip mechanism mainly consists of an anti-slip base and a mounting groove. Its compact and reasonable structural design facilitates coordination with the overall structure of the jack. The anti-slip base, installed below the fixed base, is the part in direct contact with the ground, increasing friction and enhancing support stability. The anti-slip base is typically made of wear-resistant and pressure-resistant high-strength alloy steel or composite rubber to ensure a firm grip on the ground, preventing displacement or slippage of the jack, even in wet, soft, or sloping terrain. The mounting groove, located on the upper surface of the anti-slip base, is identical in shape and size to the fixed base, allowing the fixed base to be securely embedded within it, preventing displacement or loosening under load, thus further enhancing the overall structural strength and safety. This modular design not only enhances the jack's anti-slip performance but also facilitates replacement and maintenance, increasing the device's applicability and service life.
[0009] The anti-slip mechanism also includes anti-slip grooves on both sides of the mounting slot to further enhance the friction between the base and the ground, thereby improving the stability and safety of the entire jack during use. The anti-slip grooves are linearly arranged and evenly spaced, effectively distributing force and preventing slippage under pressure. Each anti-slip groove has a triangular cross-sectional shape; this geometry helps to create an embedded interlocking effect, giving the base stronger grip on soft or granular surfaces. Simultaneously, the symmetrical arrangement of the anti-slip grooves on both sides not only ensures structural force balance but also enhances the jack's anti-slip capability in different directions, further optimizing its adaptability and practicality in various complex terrains.
[0010] The anti-slip mechanism also includes supporting ramps, anti-slip components, and anti-slip nails to further enhance the device's anti-slip and stability during use. Supporting ramps are located on both sides of the anti-slip base, and their inclined shape creates a pressure-dispersing guiding structure when the jack is under load, enhancing the base's adhesion to the ground. The anti-slip components are installed in the middle of the anti-slip groove, serving as the load-bearing components for the anti-slip nails, transmitting pressure and maintaining structural stability. The anti-slip nails are installed below the anti-slip components; the nail bodies are made of high-strength metal, and the bottom of the anti-slip nails is designed with a conical head for easy insertion into soft ground such as soil or gravel, achieving a more secure ground anchoring effect. This multi-layered anti-slip structure design significantly improves the safety and adaptability of the jack in complex road conditions.
[0011] The anti-slip base includes anti-slip textures, telescopic grooves, and a storage slot. The overall structure is designed to enhance the device's grip and functional expandability under different terrain conditions. The anti-slip textures are located on the bottom surface of the base to increase friction with the ground and prevent slippage. The inclined arrangement of these textures helps to penetrate the ground under stress, improving stability. The telescopic grooves are located inside the mounting slot and can be used to install telescopic structural components, allowing the base to be flexibly adjusted to different heights or terrains. The storage slot is located below the telescopic grooves and is used to accommodate the retracted portion of the telescopic components, allowing the components to be neatly stored when not in use, reducing space occupation. Through the synergistic cooperation of the anti-slip textures and the groove structure, the practicality and engineering adaptability of the anti-slip base are significantly improved, meeting the stable support requirements of engineering vehicles under complex working conditions.
[0012] The anti-slip assembly includes a compression plate, a telescopic column, a support spring, a mounting plate, and a telescopic plate. Its structural design aims to enhance the jack's cushioning and anti-slip performance during use. The compression plate, mounted above the anti-slip base, is a key component for force transmission. A telescopic column is located in the middle, allowing it to move up and down under external force. A support spring is connected below the telescopic column, with its upper end pressed against the compression plate, providing a counter-elastic force when the telescopic column is compressed, thus buffering and absorbing shock. The lower end of the support spring connects to the mounting plate, stabilizing the entire anti-slip structure and ensuring it remains stable during operation. Below the mounting plate is a telescopic plate, which can flexibly extend or retract to adapt to changes in terrain, further enhancing its contact with the ground. Through the multi-stage coordination of this anti-slip assembly, the jack possesses excellent adaptability and stability.
[0013] The support springs are arranged in a circular array, evenly distributed around the telescopic column. This structural design enables multi-point balanced support under load, effectively dispersing the concentrated load transmitted from the vehicle's weight. The circular array arrangement enhances the vertical stability and cushioning performance of the entire anti-slip assembly, preventing structural shifts or imbalances caused by single-point stress, thereby improving the jack's safety and lifespan in complex terrain.
[0014] The beneficial effects of this utility model are as follows:
[0015] (1) The anti-slip engineering vehicle jack provided by this utility model has excellent stability and anti-slip performance, and is particularly suitable for soft, slippery or uneven construction ground. By setting an anti-slip base, anti-slip texture, anti-slip nails and multi-level anti-slip components, the device can firmly grip the ground under complex terrain conditions, avoiding dangerous situations such as lateral displacement, slippage or sinking under force, and significantly improving the safety and reliability of the jack. At the same time, through the adjustable telescopic structure and support spring design, the device's adaptability to different vehicle chassis heights and load-bearing conditions is improved, expanding its application range. This device is particularly suitable for engineering machinery, off-road vehicles or field maintenance scenarios, overcoming the problems of traditional jacks' strong dependence on terrain and poor stability.
[0016] (2) This utility model adopts a modular design concept, which facilitates the disassembly, maintenance and replacement of various components, reduces maintenance costs and improves service life. The support springs are arranged in a circumferential array, combined with the central telescopic column and the bottom telescopic plate, so that the jack has a stronger balanced support force and impact resistance when bearing heavy loads, effectively reducing the risk of structural deformation. The conical anti-slip nails and inclined anti-slip texture design in the anti-slip component further enhance the gripping force with the ground and improve the anti-slip performance of the whole machine. Through the organic combination of mechanical and elastic structures, not only is good load response achieved, but overall operating efficiency is also improved, providing a safer and more reliable technical guarantee for the lifting and support operations of field engineering vehicles.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] like Figure 1-6 As shown, an anti-slip engineering vehicle jack mainly comprises several components, including a fixed base 1, support rods 2, fixing blocks 3, adjusting shafts 4, drive ends 5, lifting blocks 6, and an anti-slip mechanism 7. The fixed base 1 is located at the bottom of the entire device, serving as a support foundation to ensure stable ground contact during use. The support rods 2 are vertically mounted above the fixed base 1 to bear vertical loads from the vehicle and connect the upper and lower structures. The upper end of the support rods 2 is connected to the fixing blocks 3, which have two support rods 2 on them to enhance structural stability and load-bearing capacity. An adjusting shaft 4 passes between the two fixing blocks 3 to adjust the jack's support height and angle. One end of the shaft is connected to the drive end 5, which can be equipped with a motor for automatic control or a manual crank for manual operation, improving the device's adaptability and flexibility. The lifting block 6 is located at the top of the jack structure and is a key component that contacts the bottom of the vehicle and transmits lifting force. To ensure stable support on wet, soft, or sloping surfaces, the jack is equipped with an anti-slip mechanism 7 at the bottom of the fixed base 1. This mechanism increases friction with the ground and prevents slippage or sinking due to uneven force or poor ground conditions, thus improving the safety and reliability of the equipment in complex environments.
[0028] like Figure 3-4 As shown, the anti-slip mechanism 7 mainly consists of an anti-slip base 71 and a mounting groove 72. Its compact and reasonable structural design facilitates coordination with the overall structure of the jack. The anti-slip base 71 is installed below the fixed base 1, serving as the part in direct contact with the ground, increasing friction and enhancing support stability. The anti-slip base 71 is typically made of wear-resistant and pressure-resistant high-strength alloy steel or composite rubber to ensure it remains firmly attached to the ground even in complex terrain conditions such as wet, soft, or sloping surfaces, preventing displacement or slippage of the jack. The mounting groove 72 is located on the upper surface of the anti-slip base 71, and its shape and size are consistent with the fixed base 1, allowing the fixed base 1 to be securely embedded in the mounting groove 72, preventing displacement or loosening during stress, thereby further improving the overall structural strength and safety. This modular design not only enhances the anti-slip performance of the jack but also facilitates replacement and maintenance, increasing the applicability and service life of the device.
[0029] The anti-slip mechanism 7 also includes anti-slip grooves 73 on both sides of the mounting groove 72, which further enhance the friction between the base and the ground, thereby improving the stability and safety of the entire jack during use. The anti-slip grooves 73 are linearly arranged and evenly spaced, which can effectively distribute the force and prevent the device from slipping under pressure. The cross-sectional shape of each anti-slip groove 73 is designed as a triangle. This geometric structure helps to form an embedded interlocking effect, giving the base a stronger grip on soft or granular surfaces. At the same time, the anti-slip grooves 73 on both sides are arranged symmetrically, which not only ensures the balance of structural forces, but also improves the jack's anti-slip ability in different directions, further optimizing its adaptability and practicality in various complex terrains.
[0030] The anti-slip mechanism 7 also includes supporting ramps 74, anti-slip components 75, and anti-slip studs 76, further enhancing the anti-slip and stability capabilities of the device during use. Supporting ramps 74 are located on both sides of the anti-slip base 71. These ramps are inclined, creating a pressure-dispersing guiding structure when the jack is under load, enhancing the base's adhesion to the ground. The anti-slip component 75 is installed in the middle of the anti-slip groove 73, serving as the load-bearing component for the anti-slip studs 76, transmitting pressure and maintaining structural stability. The anti-slip studs 76 are installed below the anti-slip component 75. The studs are made of high-strength metal, with a tapered head 761 at the bottom for easy insertion into soft ground such as soil or gravel, achieving a more secure ground anchoring effect. This multi-layered anti-slip structure design significantly improves the safety and adaptability of the jack in complex road conditions.
[0031] like Figure 5 As shown, the anti-slip base 71 includes anti-slip textures 711, telescopic grooves 712, and a storage groove 713. The overall structure aims to improve the device's grip and functional expandability under different terrain conditions. The anti-slip textures 711 are located on the bottom surface of the anti-slip base 71 to enhance friction with the ground and prevent slippage. The textures are angled, which helps to cut into the ground during stress, improving stability. The telescopic grooves 712 are located inside the mounting groove 72 and can be used to install telescopic structural components, allowing the base to be flexibly adjusted to different heights or terrains. The storage groove 713 is located below the telescopic groove 712 and is used to accommodate the retracted portion of the telescopic components, allowing the components to be neatly stored when not in use, reducing space occupation. Through the synergistic cooperation of the anti-slip textures 711 and the groove structure, the practicality and engineering adaptability of the anti-slip base 71 are significantly improved, meeting the stable support requirements of engineering vehicles under complex working conditions.
[0032] like Figure 6As shown, the anti-slip assembly 75 includes a compression plate 751, a telescopic column 752, a support spring 753, a mounting plate 754, and a telescopic plate 755. Its structural design aims to improve the jack's cushioning and anti-slip performance during use. The compression plate 751, mounted above the anti-slip base 71, is a key component for force transmission. A telescopic column 752 is located in the middle, allowing it to move up and down under external force. The support spring 753 is connected below the telescopic column 752, with its upper end pressed against the compression plate 751, providing a counter-elastic force when the telescopic column 752 is compressed, thus buffering and absorbing shock. The lower end of the support spring 753 is connected to the mounting plate 754, providing a stable connection to the entire anti-slip structure and ensuring it does not loosen during operation. Below the mounting plate 754 is the telescopic plate 755, which can flexibly extend or retract when the terrain changes, further enhancing its contact with the ground. Through the multi-stage coordination of this anti-slip assembly 75, the jack possesses excellent adaptability and stability.
[0033] The support springs 753 are arranged in a circular array, evenly distributed around the telescopic column 752. This structural design enables multi-point balanced support under load, effectively dispersing the concentrated load transmitted from the vehicle's weight. The circular array arrangement enhances the vertical stability and cushioning performance of the entire anti-slip assembly 75, preventing structural displacement or imbalance caused by single-point stress, thereby improving the safety and service life of the jack in complex terrain.
[0034] In operation, the operator places the jack under the location of the engineering vehicle requiring support, ensuring the anti-slip base 71 is in full contact with the ground. The lower surface of the anti-slip base 71 has inclined anti-slip grooves 711, which create friction and engagement with the ground. Triangular anti-slip grooves 73 on both sides prevent the fixed base 1 from sliding, thus improving stability. Once the jack contacts the ground, the drive end 5 begins operation. The drive end 5 can be an electric motor or a manual rocker arm, which drives the adjusting shaft 4 to rotate, causing the support rod 2 to move upwards, thereby lifting the bottom of the engineering vehicle by the lifting block 6. During this process, the telescopic column 752 drives the compression plate 751 to compress the support spring 753. The compressed spring generates a reaction force, giving the entire support system good cushioning and stability.
[0035] The working principle of this utility model is based on a combined structural design of "vertical force transmission + multi-point anti-slip + elastic buffer". The supporting force is transmitted from the lifting block 6 to the support rod 2, and then evenly distributed to the anti-slip mechanism 7 at the bottom via the fixing block 3 and the adjusting shaft 4. The anti-slip mechanism 7, through the combined action of the inclined anti-slip texture 711 under the base, the anti-slip components 75 in the anti-slip groove 73, and the anti-slip nails 76, generates strong friction and biting force when in contact with the ground, ensuring that the jack does not slip or shift under high load. At the same time, the support springs 753 are arranged in a circumferential array, which can provide multi-point buffer support when the telescopic column 752 is compressed, absorbing impact force, reducing deformation, and improving overall stability and durability. In addition, the telescopic plate 755 can be finely adjusted according to the difference in ground level to ensure that the base fits the ground and enhances adaptability to the field. Through this series of coordinated actions, safe, stable, and reliable lifting and support operations of engineering vehicles on uneven terrain are achieved.
[0036] Various modifications to this disclosure will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be given the broadest scope consistent with the principles and novel features disclosed herein.
