Description

Inclined plane support capable of continuously adjusting inclination height or angle

Technical Field

The invention relates to a slope support capable of continuously adjusting the inclination height or angle, and belongs to the field of using step slope pads, climbing bridge slope supports, solar slope supports and the like.

Background

At present, when a driver drives a vehicle to go up steps on a road or gets off the steps, people often use a slope pad, the height of the slope pad is generally fixed, and in reality, people can encounter various steps with different heights, so that the slope pad with the fixed height is not suitable for ground conditions with different heights in different sections. At present, a scissor jack inclined plane support (application number: 201310097208.5) is provided, although the inclined height can be continuously adjusted and the bearing capacity is strong, the jack type is point support, the balance and the stability are poor, at least more than two point positions are required for supporting and stabilizing, generally, one jack needs 4 rotating support arms, and two jacks need 8 rotating arms, so the scissor jack inclined plane support is complex and not practical; in addition, the rotating arm of the jack is short, and the jack is not suitable for the application occasions with large lifting range.

Disclosure of Invention

In order to solve the problem of dealing with steps with different heights, an inclined plane support capable of continuously adjusting the inclined height or angle is needed, the bearing is strong, and the lifting range is large.

The technical scheme adopted by the invention is as follows: by adopting the lifting principle of a scissor lift, only a pair (two) of scissor rotary support rods (support arms) can be used, the middle parts of the two scissor rotary support rods are connected with a common rotary shaft, one end of a support rod A and a lower guide rail are connected and fixed at one end of the lower guide rail through a rotary shaft, the other end of the support rod A is connected with a pulley or a sliding plate through the rotary shaft, and the pulley or the sliding plate can roll or slide on the upper guide rail; one end of the support rod B and the upper guide rail are connected and fixed at one end of the upper guide rail through a rotating shaft, the other end of the support rod B is connected with a pulley or a sliding plate through a rotating shaft, and the pulley or the sliding plate can roll or slide on the lower guide rail; the pulley or the sliding plate connected with the support rod B is provided with a nut hole, a screw rod is mechanically connected with the nut hole and a fixing hole (the screw rod only rotates in the hole and does not have axial displacement) or a threaded hole on the lower guide rail, the pulley or the sliding plate can be pushed to move on the lower guide rail by rotating the screw rod, the support rod B is continuously pushed to move on the guide rail, the support rod B and the support rod A rotate around a common shaft, meanwhile, the upper guide rails on the two support rods can move up and down, the upper guide rails are connected with the top ends of the inclined planes through rotating shafts or hinges, and therefore, when the upper guide rails continuously lift, the height or the angle of the inclined planes also continuously changes.

This scheme only needs to adopt two rotor arms, and is very much than jack type's simple, because the bracing piece is longer, and the lifting range of messenger is bigger. The screw rod in the scheme can also be adjusted by adopting a hydraulic push rod or a mechanical clamping position and the like.

The moving part of the moving end of the support rod on the guide rail can adopt a structure of surface-to-surface contact attached to the rail surface, and the moving part is in sliding instead of point contact or line contact structure of a circle and a plane or a cylinder and a plane to increase the bearing force, so that the middle connection is carried out through a sliding plate with a rotating shaft.

Furthermore, a motor can be added to drive the rotating part of the screw rod, and a remote control device can be added to control the forward and reverse rotation of the motor so as to control the lifting of the inclined height.

Further, the upper guide rail may be of a cylindrical structure, and the cylinder may be directly used as a rotation shaft of the bevel board or the hinge.

Furthermore, the bottom end (the lowest end) of the inclined plane plate adopts a semi-cylinder or cylindrical structure, so that the lowest end can be stably contacted with the lower contact surface after the height or the angle of the inclined plane is changed.

Furthermore, the inclined plane plate can be made into a frame structure to save materials, or the inclined plane plate is provided with reinforcing ribs to increase the structural strength.

Furthermore, the inclined plane plate adopts a bow-shaped or arc-shaped structure with small radian, so that the strength is increased.

Furthermore, an indicator light for positioning is added on the bracket to guide the direction of the inclined plane plate or play a role in warning.

Furthermore, reinforcing ribs are arranged at the upper ends of the upper guide rail and the supporting rod, so that the pressure on the upper guide rail and the supporting rod is better transmitted to the supporting rod.

Detailed Description

FIG. 1 is a schematic view of one embodiment of the present invention, FIG. 1

The middle parts of the 3 support bar B and the 4 support bar a in fig. 1 are connected by a common rotating shaft. One end of the 4 supporting rod A is connected with the 6 lower fixed seats through a rotating shaft, the 6 lower fixed seats are fixed on the 1 lower guide rail, the other end of the 4 supporting rod A is connected with the 7 upper sliding plate through a rotating shaft, and the 7 upper sliding plate can slide or move on the 2 upper guide rail. One end of the supporting rod B3 is connected with the upper fixing seat 8 through a rotating shaft, the upper fixing seat 8 is fixed on the upper guide rail 2, the other end of the supporting rod B3 is connected with the lower sliding plate 5 through a rotating shaft, and the lower sliding plate 5 can slide on the lower guide rail 1 in a displacement mode. 5, a nut hole is arranged on the lower sliding plate, and the nut hole is penetrated by a screw rod arranged on an 11 hand wheel and is mechanically connected. The screw rod on the 11 hand wheel passes through the 12 fixed blocks, the 12 fixed blocks are fixed on the lower guide rail 1, and the screw rod on the 11 hand wheel can only fixedly rotate (rotate without axial displacement) in the hole on the 12 fixed blocks by means of a positioning pin and the like. Thus, the screw rod on the 11 hand wheel can lead the lower sliding plate 5 to move and slide on the lower guide rail 1 through rotation, the lower end of the 3 supporting rod B is driven to move under the action of the rotating shaft, the 3 supporting rod B drives the 4 supporting rod A to move along with the common shaft, thus, the upper guide rail 2 is driven to move up and down, the upper guide rail 2 can be used as a rotating shaft to be inserted into a rotating hole of the hinge 9, one end of the 9 hinge is fixedly connected with the upper end of the 10 inclined plane plate, so that when the upper guide rail 2 moves up and down, the hinge 9 is also lifted by the rotating shaft and the upper end of the inclined plane plate 10 is lifted at the same time, this allows for adjustment of the tilt height or angle, since the 11 hand wheel belt screw-driven displacement is continuous, the tilt height or angle of the last correspondingly raised 10 ramp panel is also continuously adjustable over a range.

In addition, the hole on the fixed block 12 can also be a nut hole, but the nut hole on the lower sliding plate 5 and the nut hole on the lower sliding plate should be opposite threads (opposite thread directions), so that the lower sliding plate 5 can be driven to perform displacement sliding and slide faster when the hand wheel 11 is rotated. The lower bottom edge of the inclined plane plate 10 is a semi-cylinder, so that when the inclination angle of the inclined plane plate changes, the lower bottom edge can be well connected with the ground. The 10-slope panel can be made into a frame structure, and reinforcing ribs are arranged on the frame structure.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
