Description

Technical Field

[0001] The invention relates to the technical field of hydraulic tunnel construction, in particular to a hydraulic tunnel construction equipment hoisting mechanism with a cross-type support. Background Art

[0002] The construction of hydraulic tunnels is a complex and multi-step process. Before construction, it is necessary to conduct detailed geological, hydrological, topographical and geomorphic investigations and studies on the construction site to provide a basis for subsequent construction, prepare the materials required for construction, such as steel bars, cement, sand and gravel, etc., and debug the mechanical equipment required for construction. In the construction of hydraulic tunnels, a lifting mechanism is needed to move the construction equipment to the required work location, but the existing lifting equipment cannot stably move the moving workpiece. When the workpiece is lifted, the workpiece may fall down, posing certain safety hazards.

[0003] In order to overcome the above-mentioned defects, prior art 1 (publication number: CN101391726A, Chinese patent published on 2009-03-25) is a mobile hoisting mechanism. The mobile hoisting mechanism is characterized in that it contains a base, and the base contains two cross arms, one end of the two cross arms is fixedly connected together, and the other end is separated. There are directional rollers on the ends of the two cross arms that are separated, and there are universal wheels on their connecting ends, and there are vertical arms, oil cylinders and booms above the connecting ends. The lower end of the vertical arm is fixed to the connecting ends of the two cross arms, and there are transverse shaft holes on its upper end and one end of the boom. One end of the boom is hinged together with the transverse shaft hole by means of an axis, and there is a hook at the other end of the boom. There are support plates on the two cross arms near the connecting ends of the two cross arms, one end of the cylinder body of the oil cylinder is hinged on the support plate, and the other end is hinged with the boom. This mobile hoisting mechanism is small in size and can be used in places with larger spaces or smaller spaces, and its scope of application is not limited. It is especially suitable for lifting objects in small indoor and outdoor spaces that cranes cannot reach.

[0004] There is also prior art 2 (publication number: CN111947007A, Chinese patent with publication date of November 17, 2020) an agricultural machinery hoisting machine, whose structure includes a bracket, a distribution box, a lifting rope, and a hook. The distribution box is installed at the bottom of the bracket, the lifting rope cooperates with the bracket and the distribution box, and the hook is fixed at the end of the bracket. The distribution box is provided with a rotating shaft, a transmission, a turntable, and a clamping block. The rotating shaft runs through the right side of the distribution box. When the hoisting machine is used to hoist the agricultural machinery, when the lifting rope is reeled in, the surface contacts the clamping block, and the clamping block absorbs the lubricating oil on its surface to reduce the lubricating oil on the outside of the lifting rope. During the extension and retraction process of the lifting rope, the transmission and the lifting rope cannot cooperate, and the sliding speed of the lifting rope is accelerated, affecting the lifting of the machinery. The contact block is squeezed by the extrusion block inside the opening to squeeze the lubricating oil inside the oil absorption block to squeeze out and collect it, reducing the lubricating oil being absorbed inside the oil absorption block. When the lifting rope and the oil absorption block are squeezed, the lubricating oil flows out, affecting the normal absorption of the lubricating oil on the outside of the lifting rope by the oil absorption block.

[0005] Although the existing technologies 1 and 2 can perform relatively stable lifting operations on the workpiece, when the workpiece is lifted and moved, the device cannot be further fixed, and the device may be shifted in position, thereby posing certain safety hazards.

[0006] Therefore, we propose a cross-supported hydraulic tunnel construction equipment hoisting mechanism to solve the above-mentioned problems. Summary of the invention

[0014] Preferably, the lower end of the inserting plate is designed to be inclined, and the inserting plate forms an elastic structure through the first spring and the movable groove.

[0015] Preferably, the right end of the rotating shaft is fixedly connected with a gear, the right side of the upward slide is provided with an adjusting groove, and the interior of the adjusting groove is nested with a slider, and the outer surface of the slider is fixedly connected with a tooth plate, and the inner side of the adjusting groove is fixedly connected with an auxiliary rod, and the outer side of the auxiliary rod is nested with a baffle, and a second spring is fixedly connected between the inner side of the baffle and the inner wall of the adjusting groove, the upper end of the tooth plate is fixedly connected with a first strong magnetic block, and the side of the tilting block on the left is fixedly connected with a second strong magnetic block.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The staff can place the construction equipment on the upper surface of the clamping plate set inside the placement frame. At this time, the clamping plate will move downward under the influence of the gravity of the construction equipment, thereby squeezing the damping rod and causing the third spring to undergo elastic deformation. At this time, with the cooperation of the third spring and the damping rod, the force of the construction equipment during the placement process can be buffered and shock-absorbed, thereby reducing the possibility that the gravity of the construction equipment during placement will cause damage to the placement frame;

[0023] (2) When the clamping plate moves downward, it will synchronously drive the adjustment plate fixedly connected to the side to move downward along the side of the placement frame. During the downward movement, the roller arranged at the lower end of the adjustment plate will slide inward along the upper surface of the inclined block, so that the adjustment plate drives the clamping plates on both sides to move toward each other, thereby clamping and limiting the placed construction equipment. The greater the gravity of the construction equipment, the greater the force of its clamping and limiting, thereby further improving the stability of the construction equipment during the hoisting operation and reducing certain safety hazards;

[0024] (3) When the equipment is not in use, the second strong magnetic block set at the edge of the tilting block is magnetically attracted to the first strong magnetic block. When the placement frame is moved upward by the upward slide and the side slide, the second strong magnetic block will synchronously drive the toothed plate to move upward through the first strong magnetic block. At this time, the toothed plate will drive the gear meshing with it to rotate synchronously, thereby driving the rotating shaft to rotate through the gear. At this time, the rotating shaft rotates, which will synchronously cause the pushing mechanism to start running, thereby further improving the stability of the device during the lifting operation;

[0025] (4) When the rotating shaft moves, it will synchronously drive the adjusting rotating plate to rotate. At this time, the adjusting rotating plate will synchronously push the push block to move through the push rod, so that the push block drives the inserting plate to move down along the limit rod, thereby inserting into the soil to further improve the stability of the device placement;

[0026] (5) When the tooth plate moves upward, it will synchronously drive the slider to move upward along the adjustment groove. At the same time, when the slider moves, it will push the extrusion baffle to move into the inside of the adjustment groove. At this time, the baffle does not block the slider. When the slider moves to the top of the baffle, the baffle is not blocked. Driven by the elastic force of the second spring, the baffle moves and resets along the auxiliary rod. At this time, the extrusion baffle can block the slider, thereby further limiting the position of the tooth plate and further improving the stability of the insertion of the plug-in plate.
