[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] Embodiment 1:

[0028] Figure 1 and Figure 2The utility model shows a specific embodiment of a jack support device for an inclined plane, comprising a jack 4, a support plate 3 for vertically placing the jack, an adjustment mechanism 2 for adjusting the angle of the support plate, and a bottom plate 1 for supporting the adjustment mechanism and close to the inclined plane, one end of the bottom plate 1 and one end of the support plate 3 being rotatably connected through a pin 5, the adjustment mechanism 2 being located between the angle formed by the support plate and the bottom plate, and when the adjustment mechanism 2 is pushed into the angle, the angle of the support plate 3 is adjusted to keep the support plate 3 horizontal. This embodiment vertically mounts the jack on the support plate, and then uses the adjustment mechanism to make the support plate horizontal, thereby making the jack in a disguised vertical state, thereby solving the defect that the jack cannot stably perform lifting and supporting operations on the inclined plane, expanding the scope of use of the jack, and improving work efficiency.

[0029] In this embodiment, the adjustment mechanism 2 includes a wedge-shaped support slider 21, a sliding component 22 for making the wedge-shaped support slider slide on the bottom plate, and a position adjustment component 23 for adjusting the position of the wedge-shaped support slider 21 on the bottom plate 1 so that the support plate is in a horizontal state. The position adjustment component 23 makes the wedge-shaped support slider 21 slide under the action of the sliding component 22, so that the wedge-shaped support slider 21 supports the support plate 3, and stops sliding after the support plate 3 is in a horizontal state.

[0030] In this embodiment, the cross-sectional shape of the wedge-shaped support slider 21 is a right-angled trapezoid, and the inclined surface of the wedge-shaped support slider faces the angle formed by the support plate 3 and the bottom plate 1. Since the wedge-shaped support slider 21 expands the angle between the support plate 3 and the bottom plate 1 during the process of being pushed inward, the support plate can be in a horizontal state at a certain moment. At this time, the support plate 3 and the wedge-shaped support slider 21 are in line contact, that is, the line where the inclined surface of the wedge-shaped support slider intersects with the upper horizontal plane is in contact with the support plate.

[0031] In this embodiment, the sliding component 22 includes a slide rail 221 and a slide groove 222 that cooperates with the slide rail. When the slide rail is set on the bottom plate, a slide groove that cooperates with the slide rail is set at the bottom of the wedge-shaped support slider, or when the slide groove is set on the bottom plate, a slide rail that cooperates with the slide groove is set at the bottom of the wedge-shaped support slider. Regardless of whether the slide groove or the slide rail is located on the bottom plate or on the wedge-shaped support slider, it is convenient for the wedge-shaped support slider to slide more smoothly on the bottom plate. In this embodiment, two T-shaped slide rails 221 are set on the bottom plate 1, and two slide grooves 222 that cooperate with the T-shaped slide rails are set at the bottom of the wedge-shaped support slider 21. The provision of two T-shaped slide rails can enable the wedge-shaped support slider to slide stably on the bottom plate.

[0032] In this embodiment, the position adjustment component 23 includes a screw 231, one end of which is connected to the rear side of the wedge-shaped support slider 21, and the other end of which passes through a screw support seat 232. The screw support seat 232 is fixed to the end of the bottom plate 1. A threaded hole 233 for the screw to pass through is provided on the screw support seat 232, and the threaded hole 233 cooperates with the thread on the screw. By rotating the screw 231 forward, the front end of the screw 231 can be pressed against the rear side of the wedge-shaped support slider 21, so that the wedge-shaped support slider 21 moves forward, and by rotating the screw 231 backward, the wedge-shaped support slider is driven to withdraw.

[0033] In this embodiment, Figure 3 As shown, one end of the screw rod 231 is connected to the rear side of the wedge-shaped support slider 21, which means that a support hole 211 for inserting the screw rod 231 is opened on the rear side of the wedge-shaped support slider 21, a through hole 2311 is opened at the front end of the screw rod, and a limiting groove 212 is opened at the bottom of the wedge-shaped support slider 21. After the front end of the screw rod 231 is inserted into the support hole 211, it is located in the limiting groove 212. The limiting pin 213 passes through the through hole 2311 to fix the screw rod 231 in the limiting groove 212. The screw rod 231 and the support hole 211 are clearance-matched, and the center lines of the support hole 211 and the threaded hole 233 are one center line. Through the limiting groove 212, the front end of the screw is inserted into the limiting groove 212, and then the limiting pin 213 is inserted from the through hole 2311 at the front end of the screw to limit the front end of the screw in the limiting groove. When the screw rotates forward, the front end of the screw presses against the front wall of the limiting groove to move the wedge-shaped support slider forward. When the screw rotates out, the front end of the screw presses against the rear wall of the wedge-shaped support slider through the limitation of the limiting pin, driving the wedge-shaped support slider to retreat.

[0034] In this embodiment, a level is installed on the support plate to check whether the support plate is in a horizontal state at all times so as to stop the sliding of the wedge-shaped support sliding block.

[0035] In this embodiment, a lubricating oil hole 216 is opened on the upper surface of the wedge-shaped supporting sliding block 21, and the lubricating oil flows into the supporting hole 211 through the lubricating oil hole 216 to lubricate the screw.

[0036] Embodiment 2

[0037] The biggest difference from Example 1 is that in Example 1, after the support plate 3 reaches the horizontal position, there is a line contact between the support plate 3 and the wedge-shaped support slider 21, which easily causes stress concentration problems. Therefore, further improvements are needed to enable the wedge-shaped support slider to form surface contact with the support plate.

[0038] In this embodiment, Figure 2As shown, the upper half of the inclined surface of the wedge-shaped support slider 21 is also provided with a rotating slider 24 for contacting the support plate surface. The upper surface of the rotating slider 24 is a plane, and the lower surface is an arc surface. An arc groove matching the arc surface of the rotating slider is provided in the upper half of the wedge-shaped support slider 21. When the adjustment mechanism is pushed into the included angle, the upper surface of the rotating slider contacts the bottom of the support plate. The upper surface of the rotating slider is set as a plane, which facilitates the surface contact between the support plate and the wedge-shaped slider, avoiding the problem of stress concentration. At the same time, the lower surface of the rotating slider is an arc surface, and the upper half of the wedge-shaped support slider is an arc groove matching it, so that the force is more uniform, and the rotating slider is easy to rotate to a horizontal position.

[0039] In this embodiment, Figure 4 As shown, a plurality of oil grooves 214 are provided in the arc groove, and the oil grooves 214 are used to lubricate the rotating slider. As shown in the figure, two arc grooves and one linear oil groove are provided in the arc groove, which are used to lubricate the mating surfaces of the wedge-shaped supporting slider and the rotating slider.

[0040] In this embodiment, Figure 4 and Figure 5 As shown, arc-shaped slide rails 241 are arranged on both sides of the rotating slider 24, and arc-shaped slide grooves 215 cooperating with the arc-shaped slide rails are arranged on both sides of the arc-shaped groove of the wedge-shaped supporting slider 21. The arc-shaped slide rails and the arc-shaped slide grooves can make the rotating slider rotate along the arc-shaped slide grooves without deviation.

[0041] In this embodiment, when the adjustment mechanism is not working, the upper surface of the rotating slider and the inclined surface of the wedge-shaped supporting slider are in the same plane. Figure 6 As shown, the rotating slider rotates in the arc groove so that the upper surface contacts the support plate surface, and the arc of the rotating slider is greater than the arc of the arc groove on the wedge-shaped support slider. The arc surface of the rotating slider is higher than the wedge-shaped support slider on both sides so that the upper surface of the rotating slider can provide support for the support plate.

[0042] Embodiment 3

[0043] Since both the first and second embodiments are aimed at the adjustment mechanism entering the angle between the support plate and the bottom plate, they are both aimed at the case where the slope is large. When the slope is small, the adjustment mechanism does not need to enter the angle. Figure 7 As shown, the support plate is placed on the inclined surface of the wedge-shaped support slider, and the wedge-shaped support slider is directly used as the support point of the support plate to achieve angle adjustment of the support plate, thereby achieving a larger angle adjustment range.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
