Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to a support for transportation equipment. Background Technology

[0002] As a core structural component for connecting, supporting, and fixing key parts, transportation equipment brackets are widely used in the automotive, rail transit, and bridge engineering industries.

[0003] Most existing supports use knob or clasp locking mechanisms for height or angle adjustment. When the vehicle is traveling on bumpy roads or when the vehicle's posture changes due to acceleration / braking, the center of gravity of the equipment shifts, which can easily cause the support and the equipment to tilt forward, backward, or sideways. When the equipment generates an overturning moment due to road impact or its own weight, all the stress will be concentrated on one or a few locking points and hinge points, which are prone to damage.

[0004] Patent CN221139258U discloses a transportation equipment support. The above patent realizes that by setting a movable slide and a movable inner groove and their matching auxiliary structures, the equipment support can provide a certain range of adjustment function during use, and can actually adjust the width.

[0005] The aforementioned patented equipment bracket has a width adjustment function within a certain range, but it does not address the issue that the equipment's center of gravity may shift during vehicle movement, leading to the bracket and equipment tilting forward, backward, or left and right.

[0006] Therefore, this application proposes a transportation equipment support that enables the leveling shaft to drive the swing arms at both ends to move synchronously, the swing arms to pull or push the synchronous connecting rod, and the synchronous connecting rod to apply a uniform force to the support column, so that the support column drives the two ends of the bearing platform to adjust the tilt angle synchronously, thus completely avoiding the imbalance caused by uneven force at both ends during leveling. Utility Model Content

[0007] The purpose of this utility model is to provide a support for transportation equipment to solve the technical problem mentioned in the background art that when the center of gravity of the equipment shifts, the support and the equipment will tilt forward, backward or left and right, and stress concentration will cause damage.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a support for transportation equipment, comprising a base, a support column, and a load-bearing platform, wherein the support column is movably installed at the top of the outer wall of the base, and the load-bearing platform is hinged to the top of the outer wall of the support column;

[0009] The leveling shaft is rotatably installed at the bottom of the outer wall of the bearing platform. The two ends of the leveling shaft are fixedly installed with swing arms. One end of the swing arm is hinged to a synchronous connecting rod, and the synchronous connecting rod is hinged to a support column.

[0010] Preferably, a bidirectional lead screw is rotatably mounted on the top of the outer wall of the base, with lead screw nut slides sleeved at both ends of the bidirectional lead screw, and a spherical pad is provided on the top of the outer wall of the lead screw nut slide.

[0011] Preferably, one end of the bidirectional lead screw extends to the outside of the base, and one end of the outer wall of the bidirectional lead screw is connected to a handwheel.

[0012] Preferably, a preloaded spring is fitted on the outer wall of the support column, with both ends of the preloaded spring abutting against the support column and the base, respectively.

[0013] Preferably, a guide sleeve is fixedly installed at the top of the outer wall of the base, and a support column slides through the inside of the guide sleeve.

[0014] Preferably, a pivot is provided at the top of the outer wall of the bearing platform, the pivot is hinged to the clamping arm, and a torsion spring is sleeved on the outer wall of the pivot, with the two ends of the torsion spring acting on the bearing platform and the clamping arm respectively.

[0015] Preferably, the spherical pad is adapted to the concave spherical surface at the bottom of the support column.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by installing a leveling shaft, a swing arm, and a synchronous connecting rod, realizes the synchronous leveling function of the bearing platform, solves the problem of imbalance at both ends that easily occurs when the support of transportation equipment is leveled, and improves the stability of equipment use;

[0027] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a transportation equipment support, comprising a base 1, a support column 2, and a bearing platform 3. The support column 2 is movably installed at the top of the outer wall of the base 1, and the bearing platform 3 is hinged to the top of the outer wall of the support column 2. A leveling shaft 4 is rotatably installed at the bottom of the outer wall of the bearing platform 3. Swing arms 5 are fixedly installed at both ends of the leveling shaft 4. One end of the swing arm 5 is hinged to a synchronous connecting rod 6, and the synchronous connecting rod 6 is hinged to the support column 2.

[0028] Specifically, on the right side of the bearing platform 3, rotating the leveling shaft 4 clockwise drives the two swing arms 5 to rotate clockwise synchronously via a key. The end of the swing arm 5 connected to the synchronous connecting rod 6 moves downward accordingly. Under the downward pull of the swing arm 5, the synchronous connecting rod 6 stretches downward along its own axis, applying a downward pulling force to the hinge plate in the middle of the support column 2. The bottom end of the support column 2 is hinged to the base 1, and under the action of the pulling force, it rotates clockwise around the hinge seat, and the top end of the support column 2 moves to the right accordingly. The rotation angle is linearly related to the rotation angle of the leveling shaft: when the leveling shaft rotates 30°, the support column rotates about 5°. The bearing platform 3 is hinged to the top end of the support column 2. When the top end of the support column 2 moves to the right, it causes the right side of the bearing platform 3 to lift upward and the left side to relatively lower, and the transport equipment on the bearing platform 3 moves towards the center.

[0029] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a transportation equipment support, wherein the spherical pad 9 is adapted to the concave spherical surface at the bottom of the support column 2; a bidirectional lead screw 7 is rotatably mounted on the top of the outer wall of the base 1, and lead screw nut slides 8 are sleeved at both ends of the bidirectional lead screw 7, with the spherical pad 9 provided on the top of the outer wall of the lead screw nut slides 8; a rotating shaft 13 is provided on the top of the outer wall of the bearing platform 3, and a clamping arm 14 is hinged to the rotating shaft 13; a torsion spring 15 is sleeved on the outer wall of the rotating shaft 13, and the two ends of the torsion spring 15 act on the bearing platform 3 and the clamping arm 14 respectively;

[0030] Specifically, rotating the handwheel 10 clockwise causes the double-acting screw 7 to rotate clockwise. Since the threads at both ends of the screw rotate in opposite directions, the left nut slide 8 moves to the right along the T-shaped slide rail, and the right nut slide moves to the left, with the two slides moving towards each other.

[0031] The spherical pad 9 is fixed to the nut slide 8 and moves synchronously with the slide. The left spherical pad 9 pushes the left side of the concave spherical surface at the bottom of the support column 2 to the right, and the right spherical pad pushes the right side of the concave spherical surface to the left. The pushing force of the two pads forms a "correcting torque" on the support column.

[0032] The concave spherical surface at the bottom of the support column 2 is in point contact with the spherical pad 9, and can rotate flexibly around the contact point. Under the action of the corrective torque, the support column 2 rotates to the right to keep the support column 2 in a vertical state.

[0033] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a support for transportation equipment, wherein one end of the bidirectional lead screw 7 extends to the outside of the base 1, and one end of the outer wall of the bidirectional lead screw 7 is connected to a handwheel 10; the bidirectional lead screw 7 is rotatably installed on the top of the outer wall of the base 1, and lead screw nut slides 8 are sleeved at both ends of the bidirectional lead screw 7, and spherical pads 9 are provided on the top of the outer wall of the lead screw nut slides 8.

[0034] Specifically, the torsion spring 15 is fitted into the torsion spring mounting groove of the rotating shaft 13, so that one end of the torsion spring is inserted into the positioning groove inside the clamping arm 14, and the other end is aligned with the positioning groove of the bearing platform 3. The rotating shaft is inserted into the shaft hole of the clamping arm 14, and then inserted into the rotating shaft mounting seat of the bearing platform 3 as a whole.

[0035] The clamping arm 14 rotates outward around the rotating shaft 13, and the torsion spring 15 rotates synchronously with the rotating shaft and is compressed, increasing the elastic reaction force generated by the torsion spring 15.

[0036] Handwheel 10 drives the double-acting screw 7 to rotate clockwise. Since the threads at both ends of the screw rotate in opposite directions, the left screw nut slide 8 moves to the right along the T-shaped slide rail, and the right screw nut slide 8 moves to the left. The two slides move synchronously towards each other. The spherical pad 9 is fixed to the screw nut slide 8 and moves synchronously with the slide. The left pad pushes the left side of the concave spherical surface of the support column to the right, and the right pad pushes the right side of the concave spherical surface to the left. The pushing force of the two pads forms a corrective force on the support column.

[0037] The concave spherical surface at the bottom of the support column 2 is in spherical contact with the spherical pad, allowing it to rotate flexibly around the contact point. Under the action of the corrective torque, the support column slowly rotates to the right.

[0038] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a transportation equipment support, wherein a preloaded spring 11 is sleeved on the outer wall of the support column 2, and the two ends of the preloaded spring 11 abut against the support column 2 and the base 1 respectively; a guide sleeve 12 is fixedly installed at the top of the outer wall of the base 1, and the support column 2 slides through the guide sleeve 12.

[0039] Specifically, the vibration damping pads at the bottom of the base 1 attenuate the vibration, and the remaining vibration is transmitted to the guide sleeve 12. The guide sleeve 12 drives the support column 2 to vibrate synchronously. The support column 2 slides up and down along the inner wall of the guide sleeve 12. When the support column 2 slides, the preload spring 11 is compressed or stretched. The elastic reaction force generated by the spring is opposite to the vibration direction, which cancels out part of the vibration energy. The bearing platform 3 moves synchronously with the support column 2, and the silicone vibration damping pads between the equipment and the bearing platform 3 attenuate the remaining vibration.

[0040] Working principle: The transportation equipment to be fixed is placed on the top of the bearing platform. The clamping arm is rotated outward. When the clamping arm rotates around the rotating shaft, it will drive the torsion spring sleeved on the rotating shaft to rotate synchronously and be compressed. The elastic reaction force generated by the torsion spring will act in the opposite direction on the clamping arm, so that the clamping arm fits tightly against the outer wall of the equipment. At the same time, the anti-vibration pads at the bottom of the base and the silicone shock-absorbing pads on the bearing platform will initially dampen the vibration. The support column is inserted into the guide sleeve at the top of the base. The preloaded spring is sleeved on the outer wall of the support column and its two ends abut against the support column and the base respectively to buffer the vibration.

[0041] Keeping the support column vertical, turn the handwheel at one end of the double-acting screw clockwise. The handwheel drives the double-acting screw to rotate. Since the threads at both ends of the double-acting screw rotate in opposite directions, the nut slides at both ends will move towards each other along the slide rail at the top of the base. The spherical pad at the top of the nut slide moves synchronously with the slide. The left spherical pad pushes the left side of the concave spherical surface at the bottom of the support column to the right, and the right spherical pad pushes the right side of the concave spherical surface to the left. The pushing force of the two pads forms a "correcting torque" on the support column. The concave spherical surface at the bottom of the support column is in spherical contact with the spherical pad, and can rotate flexibly around the contact point. Under the action of the correcting torque, the support column is adjusted to a vertical state.

[0042] To adjust the angle of the support platform to move the equipment towards the center, rotate the leveling shaft at the bottom of the support platform clockwise. The leveling shaft drives the swing arms at both ends to rotate clockwise synchronously via a key. The end of the swing arm connected to the synchronous connecting rod moves downward. Under the downward pull of the swing arm, the synchronous connecting rod stretches downward along its own axis and applies a downward pulling force to the hinge plate in the middle of the support column. The bottom of the support column is hinged to the base and rotates clockwise around the hinge seat under the action of the pulling force. The top of the support column then moves to the right. Since the support platform is hinged to the top of the support column, the translation of the top of the support column will cause the right side of the support platform to rise upward and the left side to fall relatively downward, ultimately moving the equipment on the support platform towards the center.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
