Description

Technical Field

[0001] The utility model relates to a hydraulic jack, in particular to an anti-tilt hydraulic jack, belonging to the technical field of hydraulic jacks. Background Art

[0002] A hydraulic jack is a device that uses liquid pressure to amplify force. It has the characteristics of compact structure, stable operation, strong supporting force, and self-locking. It is mainly composed of a piston and a hydraulic cylinder. The hydraulic cylinder is filled with a certain amount of liquid and connected to a hydraulic pump. When the hydraulic pump starts working, it pushes the liquid into the hydraulic cylinder through the pressure transmission device. The entry of liquid increases the pressure inside the hydraulic cylinder, which will cause the piston to be acted upon by a force and start to move.

[0003] In the prior art, for example, a hydraulic jack disclosed in announcement number CN217201838U embeds the extension plate of the bottom fixing mechanism under the jack body downward into the ring hole of the hoop through an extension plate of the bottom fixing mechanism arranged under the jack body under the pressure pipe, and then makes the top plate above the jack body contact with the object. At this time, fixed piles are nailed into the soil layer through fixed holes on the surface of the tray, so that an additional fixing structure exists between the bottom end of the jack body and the soil layer, and then the jack body can be stably used on the soil surface with the help of the bottom fixing mechanism.

[0004] However, in actual use, during the use of the above-mentioned hydraulic jack, although it is possible to drive the fixing piles from the surface of the pallet into the interior of the soil layer and provide an additional fixing structure between the bottom end of the jack body and the soil layer, during the use of the hydraulic jack, the top of the hydraulic jack is the end that carries the object, and when the hydraulic jack lifts the object, the hydraulic rod at its top will extend outward. When the object is heavy and the hydraulic rod has been carrying the load for a long time, the hydraulic cylinder body or the hydraulic rod may tilt due to the heavy gravity. Utility Model Content

[0005] The utility model is to solve the problem of soil compactness that the hydraulic jack can be used to drive the fixing piles from the surface of the tray into the inside of the soil layer, and an additional fixing structure is provided between the bottom end of the jack body and the soil layer. However, during the use of the hydraulic jack, the top end of the hydraulic jack is one end of the object carried. When the hydraulic jack lifts the object, the hydraulic rod at the top will extend outward. When the object is heavy and the hydraulic rod has been carrying the load for a long time, the hydraulic cylinder body or the hydraulic rod may tilt due to the heavy gravity, so an anti-tilt hydraulic jack is provided.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an anti-tilt hydraulic jack, comprising a mounting plate, a jack fixedly mounted above the mounting plate and a pressure bar mechanism arranged on one side of the jack, a bearing structure is sleeved on the top of the jack, and fixing components are arranged around the mounting plate;

[0007] The bearing structure includes two symmetrically arranged connecting rings, which are fixedly installed by bolts, and a first sliding groove is opened on both sides of the connecting ring. A first bearing seat is slidably installed inside the first sliding groove, one side of the first bearing seat is rotatably connected to a connecting frame, and the side of the connecting frame away from the first bearing seat is rotatably connected to a second bearing seat.

[0008] As a further solution of the present invention: a sliding block is fixedly installed below the first bearing seat and the second bearing seat.

[0009] As a further solution of the utility model: the mounting plate is provided with a second sliding groove matching the sliding groove at the sliding groove of the second bearing seat, and the second sliding groove is provided on the mounting plate.

[0010] As a further solution of the present invention: a fixing rod is fixedly installed inside the first sliding groove and the second sliding groove, and a sliding block is slidably installed on the outside of the fixing rod.

[0011] As a further solution of the utility model: a thread is arranged on the inner side of the connecting ring, and a thread matching the thread is arranged at the connection between the jack and the connecting ring.

[0012] As a further solution of the utility model: a sponge block is fixedly installed on the top end of the connecting ring, and the inner side of the sponge block is tightly fitted with the jack.

[0013] As a further solution of the utility model: the fixing assembly includes a mounting threaded opening, a support column is mounted on the middle thread of the mounting threaded opening, and the end of the support column is a tapered structure.

[0014] The beneficial effects of the utility model are:

[0015] 1. The connecting frame is rotatably mounted by the first bearing seat and the second bearing seat, and the first bearing seat is mounted by the connecting ring, which is threadedly mounted on the outside of the jack. When the jack is lifted by the pressure lever mechanism, the connecting ring will also move along with the lifting of the jack. In this way, the jack can be supported by the connecting frame, the first bearing seat and the second bearing seat, and during the movement of the connecting ring, the sponge block on the top of the connecting ring will clean the part of the jack that has been removed, thereby reducing the adhesion of dust and stones.

[0016] 2. The fixing components are set to achieve different installation and fixing effects of the mounting plate in different load-bearing places. When used on cement ground or relatively hard places, it can be directly fixed with bolts. When it is used on relatively soft land, support columns are installed at the installation threaded ports to support the mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0023] like Figures 1 to 4 As shown, an anti-tilt hydraulic jack comprises a mounting plate 1, a jack 2 fixedly mounted above the mounting plate 1, and a pressure bar mechanism 3 arranged on one side of the jack 2, a bearing structure 4 is sleeved on the top of the jack 2, and fixing components 5 are arranged around the mounting plate 1;

[0024] The bearing structure 4 includes two symmetrically arranged connecting rings 401, which are fixed by bolts. A thread is arranged on the inner side of the connecting ring 401, and a bearing is arranged at the connection between the connecting ring 401 and the thread. A thread matching the thread is arranged at the connection between the jack 2 and the connecting ring 401. A first sliding groove 402 is provided on both sides of the connecting ring 401, and a first bearing seat 403 is slidingly installed inside the first sliding groove 402. A connecting frame 404 is rotatably connected to one side of the first bearing seat 403, and a second bearing seat 405 is rotatably connected to the side of the connecting frame 404 away from the first bearing seat 403. Embodiment 2

[0025] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0026] A slider 6 is fixedly installed under the first bearing seat 403 and the second bearing seat 405. The mounting plate 1 is provided with a second slide groove 7 matching the slider 6 at the slider 6 of the second bearing seat 405. The second slide groove 7 is provided on the mounting plate 1. The first slide groove 402, the second slide groove 7 and the slider 6 can realize the fixed moving trajectory and stable movement effect of the first bearing seat 403 and the second bearing seat 405 when driven by the connecting frame 404 and the connecting ring 401.

[0027] A fixing rod 8 is fixedly installed inside the first slide groove 402 and the second slide groove 7, and the slider 6 is slidably installed on the outside of the fixing rod 8. The fixing rod 8 can fix the moving trajectory of the slider 6 and the position of the slider 6, thereby increasing the connection between the slider 6 and the first slide groove 402 and the second slide groove 7.

[0028] A sponge block 9 is fixedly installed on the top of the connecting ring 401, and the inner side of the sponge block 9 fits tightly with the jack 2. The sponge block 9 can wipe and clean the part of the jack 2 that is moved out when the connecting ring 401 is driven, so as to prevent some dust and pebbles from entering the interior of the jack 2 after the hydraulic rod of the jack 2 is extended.

[0029] The fixing assembly 5 includes a mounting threaded opening 501, and a support column 502 is installed on the middle thread of the mounting threaded opening 501. The end of the support column 502 is a conical structure. The mounting plate 1 can use the fixing assembly 5 according to the environment in which it is used. When used in a harder place, it can directly install bolts on the mounting threaded opening 501 to fix the mounting plate 1 directly to the ground. When used on softer soil, the support column 502 can be installed on the mounting threaded opening 501, and the support column 502 and the mounting plate 1 can achieve a supporting effect on the jack 2.

[0030] Working principle: First, install the two connecting rings 401 on the outside of the hydraulic rod of the jack 2, and then use bolts to fix the two connecting rings 401. Due to gravity, the connecting rings 401 will fall directly to the top of the jack 2. Then, the mounting plate 1 can be placed in the place where it is used. When it is used on a cement floor or a relatively hard place, the mounting plate 1 can be directly fixed to the ground at the mounting threaded opening 501 with bolts. When it is used on a relatively soft land, install the support column 502 at the mounting threaded opening 501, and the mounting plate 1 is supported by the support column 502. Then, the jack can be used. When the top 2 is in use, the pressure lever mechanism 3 is pressed, and the hydraulic rod of the jack 2 is pushed upward through the pressure lever mechanism 3. When the hydraulic rod is pushed to a certain position, the thread on the outside of the hydraulic rod will drive the connecting ring 401 to move together, and the connecting ring 401 drives the first bearing seat 403 to move through the first slide groove 402, and the first bearing seat 403 drives the connecting frame 404 and the second bearing seat 405 on one side of the connecting frame 404 to move at the second slide groove 7, so that the first bearing seat 403, the second bearing seat 405 and the connecting frame 404 can realize the support effect of the protruding part of the jack 2 to avoid it from tilting when bearing.
