Description

Technical Field

[0001] This utility model belongs to the field of segment mold technology, specifically a disassembly and assembly mechanism for positioning the side mold of a segment mold. Background Technology

[0002] Currently, there are many shortcomings in the disassembly and assembly of side plates for tunnel segment molds. Specifically, the side plates are usually removed manually or with simple tools. This method is not only inefficient but also costly. Since tunnel segment molds typically have two side plates, at least two workers are needed to perform the disassembly and assembly work in shifts, which consumes a significant amount of time. In addition, the side plates themselves are quite heavy, making manual disassembly and assembly particularly time-consuming and labor-intensive.

[0003] The removed side panels also require on-site storage space, further increasing production costs and management difficulties. More seriously, due to the large size of the side panels, there is a risk of collisions between workers and on-site equipment during disassembly, which may not only affect production progress but also threaten the safety of workers.

[0004] After disassembly, the segment mold needs to be transferred to the next station for spraying release agent, and then transferred to the next station for manual reinstallation of the side plates. This repetitive action is also time-consuming and labor-intensive, which has a significant impact on the overall production cycle and limits the improvement of production efficiency.

[0005] Therefore, in view of the problems and shortcomings of the existing technology, it is necessary to provide a more efficient, safe and stable disassembly and assembly mechanism for the side mold positioning of the segment mold to overcome the above defects. Summary of the Invention

[0006] The purpose of this invention is to provide a disassembly and assembly mechanism for positioning the side mold of a segment mold, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a disassembly and assembly mechanism for positioning the side mold of a segment mold, comprising an overall frame 1 and a disassembly and assembly fixture 2; the disassembly and assembly fixture 2 comprises a slide table 201, pneumatic grippers 202, side plate grippers 203 and a transition plate 204; two sets of the disassembly and assembly fixtures 2 are symmetrically installed above the overall frame 1, and the side plate grippers 203 of the disassembly and assembly fixture 2 are correspondingly arranged in front of the side plate of the segment mold.

[0008] Preferably, the slide table 201 is equipped with a motor at its tail end for adjusting the sliding distance, and the opening and closing distance of the two side plates is determined by the relative positions of the slide table 201.

[0009] Preferably, the pneumatic gripper 202 is fixed on the adapter plate 204, and the adapter plate 204 is installed on the slide table 201 via the sliding plate 206. After air is supplied, it can drive the two gripper parts to move relative to each other, thereby causing the side plate grippers 203 symmetrically installed on the pneumatic gripper 202 to clamp or release the side plate.

[0010] Preferably, the side plate gripper 203 has a detachable polyurethane anti-slip strip on the contact surface with the side plate to increase friction and prevent the side plate from falling off.

[0011] Preferably, the overall frame 1 is provided with four sets of disassembly and assembly fixtures 2, each set of disassembly and assembly fixtures 2 corresponding to gripping two protruding positions at the bottom of the side plate.

[0012] Preferably, a sensor 205 is provided on one side of the slide rail of the slide table 201 to sense the position of the pneumatic gripper 202.

[0013] Preferably, the disassembly and assembly mechanism can be adjusted by the sliding stroke of the slide table 201 to realize bidirectional operation of automatic disassembly and assembly of the side panel.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. High efficiency and energy saving: Compared with the traditional manual disassembly method, this mechanism is located on both sides of the segment mold, which can realize synchronous disassembly, greatly improving efficiency and saving labor costs.

[0016] 2. Precise and Stable: The clamping position is fixed at the protrusion below the side plate. Disassembly can be performed once the segment mold is in place, ensuring a certain degree of precision. The use of a double-slide, double-clamping-finger structure, with polyurethane anti-slip strips installed on the inner side of the clamping fingers, increases friction, resulting in high accuracy and simple operation during assembly and disassembly.

[0017] 3. Safe and Reliable: This mechanism adopts fully automated operation. Human operation is limited to the control panel; there is no need to enter the on-site assembly / disassembly area, minimizing the risk. Furthermore, there is no need for manual placement of side panels after disassembly, avoiding space occupation and collision risks.

[0018] 4. Easy maintenance: This mechanism is an independent mechanism, and the stroke for disassembly or installation can be adjusted via the slide table, making maintenance convenient and extending its service life.

[0019] 5. Wide range of applications: This mechanism integrates the functions of disassembling and installing side panels, and is also applicable to subsequent side panel installation workstations, thus having a wide range of applications. Attached Figure Description

[0024] 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.

[0025] like Figures 1-3 This invention illustrates a specific embodiment of a disassembly and assembly mechanism for positioning the side mold of a segment mold: it includes an overall frame 1 and disassembly and assembly fixtures 2. The overall frame 1 is a steel structure frame with a transverse guide rail at the top for mounting two sets of symmetrically distributed disassembly and assembly fixtures 2 (e.g., Figure 1 As shown), the frame span covers the side plate installation area of ​​the two sets of segment molds, ensuring that the disassembly and assembly tool 2 can be aligned with the front of the two sets of side plates at the same time.

[0026] Each assembly / disassembly fixture 2 includes a slide table 201 with an integrated servo motor at the tail end, which can slide laterally along the frame guide rail. The stroke range is adjustable according to the side plate spacing (accuracy ±1mm). The slide table 201 serves as the main body of the fixture, and the opening and closing distance of the two side plates is controlled by adjusting their relative positions. The pneumatic gripper 202 is installed at the front end of the slide table 201 through the adapter plate 204 and the sliding plate 207. After air is supplied, it drives the two gripper parts to move towards each other, and the clamping force can reach more than 500N. The movement of the gripper is monitored in real time by a pneumatic pressure sensor to ensure stable clamping force.

[0027] Two sets of side plate grippers 203 are symmetrically installed at the ends of pneumatic gripper fingers 202. The contact surfaces are fitted with removable polyurethane anti-slip strips (5mm thick, friction coefficient ≥0.6), which are fixed by a dovetail groove structure. The shape of the grippers matches the raised contour of the bottom of the side plate, and the fit is ≥95% when gripping to avoid slippage. (The contact surface between the polyurethane anti-slip strip and the side plate can be serrated. Combined with the constant force control of the pneumatic gripper fingers, it can be ensured that the sliding displacement of the side plate is ≤1mm when gripping.)

[0028] The adapter plate 204 serves as the connector between the pneumatic clamp finger 202 and the slide table (201). It is made of high-strength aluminum alloy and the surface is anodized to ensure connection stability.

[0029] Sensor 205 is installed on one side of the slide rail of slide table 201. It adopts a laser displacement sensor with a detection accuracy of ±0.5mm and provides real-time feedback on the position of pneumatic clamp finger 202 to prevent overtravel collision.

[0030] Taking a dual-station synchronous disassembly operation as an example, the specific process is as follows:

[0031] 1. Initial state: The two sets of segment molds are conveyed to the designated station by the conveyor belt, triggering the station sensor, and the system confirms that the mold is in place; the pneumatic gripper 202 is in the open state, and the slide table 201 is in the standby position on both sides of the frame (about 300mm away from the side plate).

[0032] 2. Gripper positioning and clamping: The slide table 201 drives the side plate gripper 203 to move along the guide rail towards the mold. The sensor 205 monitors the moving distance in real time until the gripper is aligned with the bottom protrusion of the side plate (error ≤ 2mm); the pneumatic gripper fingers 202 are ventilated, and the gripper fingers move towards each other at a speed of 0.1m / s, driving the gripper 203 to clamp the side plate. After the pressure sensor detects that the clamping force has reached the preset value (e.g., 400N), the air supply is stopped.

[0033] 3. Side panel separation and transfer: The slide table 201 moves in the opposite direction at a speed of 0.05m / s to separate the side panel from the main body of the mold. The whole process takes about 15 seconds per set. The slide table 201 continues to move to the top of the side panel storage area, the pneumatic gripper 202 is released by air, and the side panel falls into the buffer rack, completing the disassembly process.

[0034] 4. Installation operation (reverse process): The slide table 201 moves to the side plate storage area, the gripper 203 grabs the side plate to be installed, and repeats the above positioning and clamping actions; the slide table 201 slowly pushes the side plate to the mold interface, and after the sensor detects the side plate in place signal, the gripper releases, and the installation is completed.

[0035] The applicant further declares that while the above embodiments illustrate the implementation method and apparatus structure of this utility model, this utility model is not limited to the above-described embodiments, meaning that this utility model must rely on the above methods and structures to be implemented. Those skilled in the art should understand that any improvements to this utility model, equivalent substitutions for the selected implementation methods, additions of steps, and selection of specific methods all fall within the protection and disclosure scope of this utility model.

[0036] This utility model is not limited to the above-described embodiments. All methods that use similar structures and methods to achieve the purpose of this utility model are within the protection scope of this utility model.
