Description

Technical Field

[0001] The utility model relates to the technical field of jacks, in particular to a double-plunger jack. Background Art

[0002] A jack is the simplest lifting equipment with a lifting height of less than 1m. It uses a rigid lifting piece as a working device and lifts heavy objects within the stroke through a top support or a bottom support claw. It is divided into two types: mechanical and hydraulic. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repairs and other lifting and supporting work;

[0003] When repairing heavy objects, the jack can lift the objects to a certain height, thereby providing an operating space for the staff to better perform other operations such as repairs, which brings great convenience to people's daily use.

The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] The jacks on the market are round and have only one plunger. The larger the tonnage of the jack, the larger the volume of the jack. In some special processing positions, due to space limitations and the volume limitations of the jack itself, the jack cannot be used. When a smaller jack is used, due to the limitation of tonnage, the smaller jack cannot complete the expected work well, which brings inconvenience to the staff.

[0022] In view of this, the utility model provides a double-plunger jack, which, through the cooperation of a base plate, a hydraulic device, a cross plate, a reinforcing block and an adaptable device, can use two plungers under the premise of inconvenient lifting force, thereby reducing the overall width of the jack, so as to better place the double-plunger jack into a limited space, and can also replace the corresponding top plate according to the shape of the external objects to be lifted, so as to increase the contact area with external objects, thereby reducing the probability of slipping, improving the safety performance of use, and facilitating the use of staff.

[0024] In the specific implementation process, it is worth pointing out that the hydraulic device 2 can lift external objects, the adapting device 4 can be adaptively replaced according to the shape of the external objects to be lifted, thereby avoiding the problem of small contact area due to the irregular shape of the external objects, and the adjusting device 3 can change the angles of components such as the hydraulic device 2 to avoid the double-plunger jack being subjected to a large eccentric force and thus being damaged;

[0025] Furthermore, a reinforcing block 6 is provided at the bottom of the transverse plate 5;

[0026] In the specific implementation process, it is worth pointing out that the reinforcing block 6 serves to increase the strength of the transverse plate 5 and prevent the transverse plate 5 from being deformed;

[0027] Specifically, when using the double-plunger jack, the staff first replaces the adaptation device 4 according to the shape of the object to be lifted, and then moves the double-plunger jack to a suitable position. Then the staff changes the overall angle of the double-plunger jack through the adjustment device 3, and then turns on the external power supply of the hydraulic device 2, and then it can be used.

[0028] Embodiment 2: By Figure 1 and 2 It can be seen that the hydraulic device 2 includes: a column box 201, which is installed on the top of the horizontal plate 5; two plungers 202 are provided, and both are provided inside the column box 201; a power device 203, the model of which is not specifically limited, and can meet the use requirements, and is detachably connected to the bottom of one side of the column box 201, and is detachably connected to the top of the horizontal plate 5; an oil delivery pipe 204, which is connected to the top of one side of the power device 203, and is connected to the bottom of one side of the column box 201; wherein the power device 203 can deliver hydraulic oil to the inside of the column box 201 through the oil delivery pipe 204, and then lift the plunger 202;

[0033] Specifically, on the basis of the above-mentioned embodiment 1, when it is necessary to change the overall angle of the double-piston jack, the staff twists the threaded rod 304, and the threaded rod 304 drives the clamping plate 303 to move along the inside of the base plate 1. At this time, the clamping plate 303 can drive the rotating part 305 close to the side of the threaded rod 304 to move, and then drive the slide plate 302 to slide along the outer wall of the slide rail 301. At this time, the cross plate 5 can be driven to rotate along the rotating part 305 away from the side of the threaded rod 304, thereby changing the angle of components such as the hydraulic device 2.
