Description

Technical Field

[0001] This utility model relates to the field of monorail crane docking technology, specifically to a quick docking clamp for a pneumatic monorail crane. Background Technology

[0002] A monorail crane is a material handling equipment that uses an overhead monorail as its running track and relies on its own drive device to move along the track. The equipment can drive the vehicle body to move horizontally along a preset monorail through the drive system, and cooperate with the lifting mechanism to lift and transfer materials. It has the technical advantages of compact structure, flexible operation and high space utilization. It is widely used in mine underground roadways, large factory workshops, warehousing and logistics centers and other scenarios, and is especially suitable for long-distance, fixed-point material transportation tasks in narrow working spaces. However, considering that when assembling a monorail crane, two slides are usually used to support the track sections to be connected, and the position is adjusted by moving the slides through a slider, the movement accuracy of the existing slides mainly relies on manual control. The gap between the slider and the slide can easily cause deviation during track connection. Moreover, there is a lack of an effective positioning mechanism, which requires repeated adjustments, wasting time and affecting the connection quality. Therefore, those skilled in the art provide a pneumatic monorail crane quick connection fixture to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a quick docking clamp for a pneumatic monorail crane, thereby solving the problems mentioned in the background section of the prior art.

[0004] This utility model provides the following technical solution: a quick docking clamp for a pneumatic monorail crane, including a base, with two sets of docking components fixedly connected to the inner cavity of the base. The two sets of docking components can move towards each other along the inner cavity of the base to adapt to and drive two sets of suspension rails on the slide to approach each other, thereby achieving precise splicing of the two sets of suspension rails. A guide and force-saving component is fixedly connected to the bottom of the base. The guide and force-saving component slides with the docking components to assist the two sets of docking components in completing the docking action of the suspension rails.

[0005] As a preferred embodiment of the above technical solution, a slide rail is fixedly connected inside the base, and a slide groove is formed on the surface of the slide rail. The inner wall of the slide groove is slidably connected to two sets of docking components.

[0006] As a preferred embodiment of the above technical solution, the docking assembly includes a slider that slides on the inner wall of the groove, a slide plate is fixedly connected to the end of the slider, a pulley frame is fixedly connected to the bottom of the slide plate, a pulley is rotatably connected inside the pulley frame, and a push plate is fixedly connected to the bottom of the pulley frame.

[0007] As a preferred embodiment of the above technical solution, a cylinder is fixedly connected to the inner cavity of the base, a connecting frame is fixedly connected to the output end of the cylinder, and the connecting frame is fixedly connected to the slide plate.

[0008] As a preferred embodiment of the above technical solution, the guiding and labor-saving component includes a mounting plate fixedly connected to the bottom of the base, and a pulley plate fixedly connected to the surface of the mounting plate, wherein the pulley plate is slidably connected to the pulley.

[0009] As a preferred embodiment of the above technical solution, a hoisting bracket is fixedly connected to the top of the base.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a hoisting bracket at the top of the base to hoist the entire assembly to the preset position of the monorail crane slide and rigidly fix it, ensuring that the base does not shift during operation. The cylinder drives the docking assembly to move in opposite directions along the slide groove of the inner slide rail of the base, causing the push plate to engage with the end of the rail and push them axially closer until the splicing end faces are completely fitted. At the same time, the pulley rolls on the pulley plate of the guide and labor-saving assembly, converting sliding friction into rolling friction, which significantly reduces driving resistance. The rigid guidance of the slide groove ensures the precise movement trajectory of the docking assembly, effectively guaranteeing the coaxiality and splicing accuracy of the rail splicing. The rolling friction design of the guide and labor-saving assembly greatly reduces driving energy consumption, making operation more labor-saving and efficient. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figures 1-4 As shown, this utility model provides a technical solution: a quick docking clamp for a pneumatic monorail crane, including a base 1, two sets of docking components 2 are fixedly connected to the inner cavity of the base 1, the two sets of docking components 2 can move towards each other along the inner cavity of the base 1 to adapt to and drive the two sets of hanging rails on the slide to approach each other, so as to achieve precise splicing of the two sets of hanging rails; a guide and effort-saving component 3 is fixedly connected to the bottom of the base 1, the guide and effort-saving component 3 slides with the docking component 2 to assist the two sets of docking components 2 in completing the docking action of the hanging rails; The base 1 is fixedly installed in the preset position of the slide of the monorail crane, ensuring that the central axis of the two sets of docking components 2 is collinear with the central axis of the two sets of rails to be spliced. At the same time, the guide force-saving component 3 is in the initial reset state, the two sets of docking components 2 maintain the maximum distance, and the docking components 2 are driven to move. The two sets of docking components 2 move in opposite directions along the inner cavity of the base 1. During the opposite movement, the docking components 2 respectively engage and position with the ends of the two sets of rails to be spliced ​​on the slide. Then, the opposite driving force is continuously applied to push the two sets of rails to approach each other axially until the splicing end faces of the two sets of rails are completely attached, realizing the coaxial splicing of the rails.

[0015] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, a slide rail 10 is fixedly connected inside the base 1. A slide groove 101 is opened on the surface of the slide rail 10. The inner wall of the slide groove 101 is slidably connected to two sets of docking components 2. In the initial state, the two sets of docking components 2 are respectively placed at both ends of the slide groove 101, providing initial bearing and guiding foundation for the docking of the hanging rail. After the docking operation is started, the two sets of docking components 2 move in opposite directions along the extension direction of the slide groove 101. With the limiting effect of the slide groove 101, the movement trajectory of the docking components 2 is ensured not to deviate, ensuring the coaxiality of the hanging rail splicing. After the hanging rail docking is completed, the docking components 2 can move back to their original positions along the slide groove 101. The slide groove 101 continuously provides stable sliding guidance constraint for them.

[0016] As one embodiment of this example, please refer to Figure 3. The docking assembly 2 includes a slider 230 that slides on the inner wall of the slide groove 101. A slide plate 23 is fixedly connected to the end of the slider 230. A pulley frame 24 is fixedly connected to the bottom of the slide plate 23. A pulley 240 is rotatably connected inside the pulley frame 24. A push plate 25 is fixedly connected to the bottom of the pulley frame 24. When docking is started, the slider 230 slides along the slide groove 101 and drives the slide plate 23 to move synchronously. The slide plate 23 transmits power through the pulley frame 24, causing the pulley 240 to roll along the corresponding structure of the guide force-saving assembly 3. During the movement, the push plate 25 moves synchronously with the pulley frame 24 until it abuts against the end of the hanging rail to be spliced. The push plate 25 continuously applies a pushing force to push the two sets of hanging rails closer to each other until the splicing end faces of the hanging rails are completely in contact. During the reset phase, the slider 230 drives the slide plate 23 to slide in the opposite direction. The push plate 25 disengages from the hanging rail with the pulley frame 24, and finally drives the docking assembly 2 to reset to the initial position.

[0017] As one implementation method in this embodiment, please refer to Figure 3 As shown, a cylinder 21 is fixedly connected to the inner cavity of the base 1, and a connecting frame 22 is fixedly connected to the output end of the cylinder 21. The connecting frame 22 is fixedly connected to the slide plate 23. The cylinder 21 receives the drive signal and outputs axial drive force. The drive force is transmitted to the slide plate 23 through the connecting frame 22. Under the action of the drive force, the slide plate 23 drives the slider 230 to slide along the slide groove 101, thereby driving the entire docking assembly 2 to move in opposite directions. When the hanging rail is accurately spliced, the cylinder 21 stops outputting positive drive force and maintains the current state to ensure the stability of the hanging rail splicing.

[0018] As one implementation method in this embodiment, please refer to Figure 3 As shown, the guide and effort-saving component 3 includes a mounting plate 31 fixedly connected to the bottom of the base 1. A pulley plate 32 is fixedly connected to the surface of the mounting plate 31, and the pulley plate 32 is slidably connected to the pulley 240. When the docking component 2 moves, the pulley frame 24 drives the pulley 240 to move synchronously. The pulley 240 rolls in contact with the surface of the pulley plate 32, converting the sliding friction between the docking component 2 and the base 1 into rolling friction, reducing the resistance during the movement of the docking component 2, and achieving the effort-saving effect. During the entire mutual and opposite movement of the docking component 2, the pulley 240 always rolls along the surface of the pulley plate 32, continuously providing low-resistance guidance for the movement of the docking component 2, and ensuring the high efficiency of the driving process.

[0019] As one implementation method in this embodiment, please refer to Figure 1 As shown, a hoisting bracket 11 is fixedly connected to the top of the base 1; during the installation stage, the base 1 is hoisted as a whole to the preset installation position of the monorail crane slide through the hoisting bracket 11 to ensure that the base 1 has no relative displacement during the docking operation.

[0020] Working principle: During operation, the base 1 is first precisely hoisted to the preset installation position of the monorail crane slide using the hoisting bracket 11. Bolts and other fasteners are used to rigidly fix the base 1 to the slide, ensuring that the central axis of the two sets of docking components 2 is precisely collinear with the central axis of the rail to be spliced, thus avoiding docking misalignment from the outset. At this time, the two sets of docking components 2 are at their extreme positions at both ends of the slide groove 101, maintaining maximum spacing. The guide and force-saving component 3 is simultaneously in its initial reset state. The pulley 240 and pulley plate 32 remain in contact without deformation under stress. After starting the operation, the cylinder 21 receives the control signal and outputs a stable axial driving force. This driving force is evenly transmitted to the slide plate 23 through the connecting frame 22, causing the slider 230 to move smoothly in opposite directions along the slide groove 101. During the movement, the pulley... The frame 24 synchronously drives the pulley 240 to roll along the surface of the pulley plate 32, converting the sliding friction between the docking component 2 and the base 1 into low-resistance rolling friction, which not only saves effort but also ensures the smoothness of the movement trajectory. As the docking component 2 continues to approach, the push plate 25 moves synchronously with the pulley frame 24 until it precisely abuts against the ends of the two sets of hanging rails to be spliced. Then, the push plate 25 continuously applies axial thrust under the action of driving force, pushing the two sets of hanging rails to approach smoothly along the central axis until the splicing end faces of the hanging rails are completely fitted without gaps, achieving coaxial splicing. After the splicing is completed, the cylinder 21 maintains the current driving force output state, providing continuous clamping and locking force for the docking component 2, effectively preventing the hanging rails from shifting due to vibration and bumps in subsequent lifting operations, and ensuring the long-term stability of the splicing structure.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
