Description

Technical Field

[0001] This utility model relates to the field of underground transportation equipment technology, specifically a quick-release monorail auxiliary transport gantry. Background Technology

[0002] As an important underground transportation equipment, monorail cranes are mainly used for the installation and retraction of working faces and the transportation of large and large quantities of materials. However, the handling of small materials still relies entirely on manual labor, especially on long uphill sections. This not only consumes a lot of physical strength of the workers but also poses a high safety risk. In order to reduce the labor intensity of employees and improve the safety conditions of operation, we have independently designed a small material auxiliary transportation crane suitable for single-person operation. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release monorail auxiliary transport gantry to solve the problem that the handling of small materials still relies entirely on manual carrying, especially on long uphill sections, which not only consumes a lot of physical strength of the workers but also poses a high safety risk.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-release monorail auxiliary transport gantry, comprising a scissor lift, rollers, and a braking device. The scissor lift consists of an outer scissor and an inner scissor, which are a pair of spaced-apart support rods. The inner scissor is located inside the outer scissor.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figure 1-3 One embodiment of this utility model is a quick-release monorail auxiliary transport gantry, comprising a scissor lift 1, rollers 2, and a braking device 3. The scissor lift 1 is constructed by welding two δ10mm steel plates together and bolting them in the middle. It can rotate freely, providing fixed support. It consists of an outer scissor lift and an inner scissor lift, which are a pair of spaced-apart support rods. The inner scissor lift is located inside the outer scissor lift. The support rods of the inner and outer scissor lifts are hinged at the middle. Extension sections are provided at the front and rear ends of the top of the outer and inner scissor lifts, perpendicular to them. Rollers 2 are installed between the corresponding end faces of the extension sections. The rollers 2 on the corresponding end faces of the extension sections of the outer and inner scissor lifts are on the same axis, consisting of four Φ16 rollers 2, used for the lift to slide on the monorail track. The operation transforms sliding friction into rolling friction, making single-person traction extremely labor-saving and minimizing track wear. Rollers 2 are located on the left and right ends of the monorail track. A positioning rod 4 is hinged to the bottom of the outer scissor. A positioning groove is formed on the side of the positioning rod 4 away from the hinge point. The positioning groove cooperates with the limiting rod 6 on the inner scissor. Through the cooperation of the positioning groove, a simple and reliable mechanical locking mechanism is formed. When the scissor frame 1 is extended to the working width and placed on the track, the positioning rod 4 overlaps the limiting rod 6 for positioning. The pulley group on the frame is stably placed on the track, preventing jamming due to excessively tight roller spacing or falling due to excessively loose spacing. A braking device 3 is installed on the outer shear and spaced apart from the roller 2. It includes a fixed plate, a guide sleeve 301, a pull rod 302, a retaining ring 303, and a spring 304. The fixed plate is fixedly connected to the outer shear. The top of the fixed plate is connected to the guide sleeve 301, which houses the pull rod 302. The bottom end of the pull rod 302 passes through the guide sleeve 301 and the fixed plate. The top end abuts against the monorail track connection buckle, and the bottom end is connected to a pull rope. When the pull rope is pulled downwards, it causes the pull rod 302 to move downwards. Simultaneously, the retaining ring 303 is displaced, compressing the spring 304. Overcoming the spring force releases the brake, allowing the equipment to move. When stopping, the triangular handle is released, and the compressed spring 304 causes the retaining ring 303 to move upward, simultaneously causing the pull rod 302 to move upward and reset. The pull rod 302 then presses against the track connecting buckle or small handle, thus achieving the emergency braking function. The bottom end of the pull rope is connected to the triangular handle, and a retaining ring 303 is provided on the outer circumference of the pull rod 302. The retaining ring 303 and... The inner wall of the guide sleeve 301 is fitted together. A spring 304 is provided between the retaining ring 303 and the bottom end of the inner wall of the guide sleeve 301. One end of the spring 304 abuts against the retaining ring 303, and the other end abuts against the guide sleeve 301. A connecting screw 5 is vertically provided at the bottom cut-off end of the outer and inner shears. The connecting screw 5 is screwed into the pre-set internal thread hole on the outer and inner shears. The connecting screws 5 on the outer and inner shears are connected by a connector, which includes a hanging chain or a connecting plate, and is vertically screwed to the bottom of the scissor lift 1. This part is used to connect with the connectors, facilitating connection and disassembly. Different connectors are selected according to the weight of the materials. When lifting lighter or irregular materials, the hanging chain is connected to the connecting screw 5. The materials can be pre-tied and hooks are set on the materials to connect with the hanging chain. When lifting heavier or regular materials, the connecting plate with the pre-drilled through hole is connected to the connecting screw 5. Then, the connecting screw 5 is screwed into the outer and inner shears. The bottom end of the connecting plate can be equipped with hooks or pre-drilled holes for lifting. During installation, first open the outer and inner shears to the desired angle, then place roller 2 on the track and adjust the angles of the outer and inner shears simultaneously. Next, rotate the positioning rod 4 and position it on the limit rod 6. Then, install the connecting parts according to the hoisting requirements. When moving, pull down the triangular handle to pull the lever 302 downward, releasing the brake. Manually push the hoist to move it. When it reaches the designated position, release the triangular handle. The compressed spring 304 drives the retaining ring 303 upward, simultaneously driving the lever 302 upward to reset. The lever 302 presses against the track connecting buckle or small handle to achieve braking and unload the hoisted material. Then, rotate the positioning rod 4 to unlock it and remove the device or manually push the device back to the required hoisting position.
