Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 6, the utility model provides a heightening anti-sinking horizontal jack, which comprises a jack body 1, an anti-sinking component and a heightening device component 2; the jack body is provided with an oil pump component 3, a lifting arm 4, a lifting handle 5 and a lifting hand 6; the anti-sinking assembly comprises heightening wheels 21 and a supporting bottom plate 101, wherein the heightening wheels 21 are arranged at two ends of the jack body 1 and are used for increasing the contact area between the jack body 1 and the ground; a tray support 401 is mounted at the top of the lifting arm 4, a first tray 7 is mounted on the tray support 401, and the height increasing device part is mounted on the first tray 7; the heightening device component 2 comprises a base 201 assembled with the first tray 7, and a supporting pipe 202, an adjusting pipe 203, a top plate 204 and a latch piece 205 which are arranged on the base 201; the supporting tubes 202 are welded on the base 201, positioning holes 206 are formed in the supporting tubes 202, and the number of the adjusting tubes 203 is more than one; the adjusting pipe 203 is arranged inside the supporting pipe 202 or inside the adjusting pipe 203; the adjusting pipe 203 is provided with more than one adjusting hole 207, the top of the adjusting pipe 203 is welded with a top disc 204, and the adjusting pipe 203 and the supporting pipe 202 penetrate through the positioning hole 206 and the adjusting hole 207 through a bolt piece 205 to control the telescopic height of the adjusting pipe; the telescopic height of the adjusting pipe 207 is controlled by the bolt piece 205 passing through the adjusting hole 207 between the adjusting pipe 203 and the adjusting pipe 203.
Referring to fig. 1, 2, 5 and 6, a bump 701 is disposed on the first tray 7, a groove 702 is formed between the bumps, and a fastening groove 703 is disposed below the bump 701; the base 201 is provided with a clamping key 208 matched with the clamping groove 702, and the base 201 is clamped in the clamping groove below the convex block 701 through the clamping key 208 and fixed on the first tray 7; the jack body 1 is also provided with a positioning plate 8 for fixing the heightening device component 2; the positioning plate 8 is a positioning plate 8 with bolt fixing holes or a positioning plate 8 with the same structure as the first tray.
Referring to fig. 2, the jack body 1 is further provided with a connecting rotating shaft 102 connected with the supporting wheel 21.
When the jack is used, if a lower chassis vehicle is lifted, a heightening device part is not required to be installed; if a higher chassis vehicle is lifted, the clamping key on the base of the heightening device part is aligned to the groove on the first tray, and then the heightening device part is rotated to place the clamping key into the clamping groove below the bump, so that the heightening device part is fixed on the first tray; then adjusting the telescopic length of the adjusting pipe according to the height of the chassis; after the adjusting pipe is adjusted, the lifting handle is operated to enable the oil pump component to act to drive the lifting arm and the heightening component to ascend, so that the jacking disc is jacked on a vehicle chassis, a vehicle is jacked up for maintenance, and after maintenance is finished, the jack is decompressed to reset; the ware part that increases is rotated after reseing, makes the card key rotatory in the recess position, then will increase the part and take off, in retrieving the stay tube with the regulating tube, fixes a position with bolt part, later fix on the locating plate again.
When the jack works on a soft texture surface and the wheels sink, the contact area with the ground is enlarged due to the heightened wheels, so that the jack plays a role of supporting the jack body in the first step; in order to reduce the bearing force of the wheels on the reaction force, when the heightened wheels sink to the position where the supporting bottom plate is contacted with the ground, the supporting bottom plate further increases the contact area with the ground, the effect of supporting the jack body in the second step is achieved, and the bearing force of the heightened wheels on the reaction force is reduced, so that the problem that the reaction force acts on the connecting rotating shaft is solved, and the problem that the later-stage jack is influenced by the deformation of the connecting rotating shaft after long-term use is solved; the supporting bottom plate arranged at the bottom prevents the bottom of the jack from being polluted after the jack sinks, and also avoids the problem that the jack cannot normally perform pressure relief and reset actions after the jack sinks, so that the stability of the vehicle during lifting is ensured; the safety performance in use is improved;
the telescopic height of the adjusting pipe is controlled by the adjusting pipe and the supporting pipe through the bolt piece penetrating through the positioning hole and the adjusting hole, and the telescopic height of the adjusting pipe is controlled by the bolt piece penetrating through the adjusting hole between the adjusting pipe and the adjusting pipe, so that the problems that the vehicle with a higher chassis cannot be lifted or the lifting height is insufficient due to the limited heights of the tray and the bracket, the limited distance between the bracket and the telescopic rod and the limited diameter of the middle threaded hole between the tray and the bracket are avoided; in addition, the adjusting time of the telescopic height of the heightening device part is reduced, so that the working efficiency is improved, and the maintenance speed of the vehicle is accelerated;
through the cooperation between card key and recess, lug and the buckle groove to made things convenient for and increased the ware part and fixed on first tray, and then realized quick dismouting and increased the ware part.
When the height increasing device part is not suitable for use in the utility model, the height increasing device part is fixed in two ways, one way is that the bolt passes through the positioning plate and is connected with the height increasing device part, thereby completing the positioning of the height increasing device part; the other is that the structure of the positioning plate is set to be the same as that of the first tray, and the positioning of the height increaser part is completed through the matching of the clamping key and the groove, the convex block and the clamping groove; the second positioning plate needs to penetrate through the middle of the second positioning plate through a bolt and is fixedly connected with the jack body.
The utility model discloses, avoided the jack body at soft ground during operation, the technical problem of sinking to solved and can not lift rising chassis vehicle and lift high not enough, and brought the inconvenient technical problem of maintenance, thereby improved jack safety in utilization.
The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
