Technical Field

[0001] This invention relates to the field of police equipment processing technology, specifically to a police isolation net welding processing equipment. Background Technology

[0002] In the field of police equipment manufacturing, police isolation netting, as an important security facility, is widely used in various scenarios requiring isolation and protection, such as large-scale event venues, crime scenes, and hazardous area isolation. Its quality and performance directly affect the effectiveness of on-site security and the safety of personnel and property.

[0003] Welding is a crucial step in the production of police isolation nets, and the quality of welding directly affects the structural strength and stability of the nets.

[0004] The existing equipment has the following disadvantages: due to the different shapes of the central frame and the isolation net, it is difficult to use a fixed device to weld and position the central frame and the isolation net, resulting in drawbacks such as difficulty in controlling welding accuracy and long assembly time.

[0005] Therefore, this application proposes a welding and processing equipment for police isolation nets to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a welding and processing equipment for police isolation nets, so as to solve the problems mentioned above, such as the difficulty in using a fixed device to weld and position the central frame and the isolation net, the difficulty in controlling welding accuracy, and the long assembly time.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a police isolation net welding processing equipment, comprising a support box and a placement platform for supporting the isolation frame to be welded, and further comprising: A fixing unit, installed on the support box, is used to fix the bottom end of the central frame and the isolation net that need to be welded to the isolation frame; A lifting rod, located at the bottom of the support box, is used to adjust the installation height of the central frame and the isolation net. A reinforcement unit is installed on the support box and located above the central frame and the isolation net, for fixing the top of the central frame and the isolation net.

[0008] The fixing unit includes: The first screw passes through the interior of the support box; Two lead screw sleeves are mounted on the first screw and extend downward through the support box; Two movable blocks, each fixed to the lower part of a corresponding lead screw sleeve, and moving together with the lead screw sleeve; Support rods are spaced apart on the movable block to support the bottom of the central frame and the isolation net.

[0009] The first screw is a bidirectional threaded rod with two one-way threads, and each one-way thread is provided with a lead screw sleeve. The two one-way threads are symmetrically arranged about the center of the first screw, and are used to control the two lead screw sleeves to move closer to each other or further away from each other.

[0010] The fixing unit further includes: A power mechanism is located on one side of the first screw and is used to control the rotation of the first screw.

[0011] The power mechanism includes: A rotating shaft is mounted on the support box; The first gear is fitted onto the rotating shaft; A handle is provided on the rotating shaft for driving the rotating shaft to rotate; The second gear is sleeved on the first screw and meshes with the first gear to transfer kinetic energy to the first screw.

[0012] The power mechanism further includes: A locking element is provided on the handle to fix the handle after adjustment; The locking element includes: The second screw is threaded onto the handle; A turntable is fixed on the side of the second screw away from the support box, and is used to drive the second screw for adjustment; An abutment plate is fixed to the side of the second screw near the support box for abutting and fixing with the support box.

[0013] The support box has a moving groove for the lead screw sleeve to move, and a guide rod for guiding the lead screw sleeve is provided inside the moving groove.

[0014] The reinforcement unit includes: A power component, located at the top of the support box, is used to drive the component to move up and down; Mounting bracket, located at the power output end of the power component; A lifting plate is located at the lower end of the mounting frame; A clamping plate, located at the lower end of the lifting plate, is used to press and fix the top of the central frame and the isolation net.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 The present invention provides a technical solution: a police isolation net welding processing equipment, including a support box 2 and a placement platform 5 for supporting the isolation frame 1 to be welded, and further including: a fixing unit 3, adjustablely mounted on the support box 2, for fixing the bottom ends of the central frame 11 and the isolation net 12 to be welded to the isolation frame 1; a lifting rod 21, mounted on the bottom end of the support box 2, for adjusting the installation height of the central frame 11 and the isolation net 12; and a reinforcing unit 4, mounted on the support box 2 and located above the central frame 11 and the isolation net 12, for fixing the top ends of the central frame 11 and the isolation net 12.

[0022] It should be noted that during the welding process of the police isolation equipment, the position of the placement platform 5 is first adjusted according to the shape of the isolation frame 1 so that the placement platform 5 can fix and support the four corners of the isolation frame 1. Then, the central frame 11, which needs to be welded and fixed to the isolation frame 1, is placed inside the isolation frame 1. Then, the support box 2 is placed inside the isolation frame 1, and the fixing unit 3 inside the support box 2 supports and fixes the bottom of the central frame 11, and the top of the central frame 11 is pressed and fixed by the reinforcing unit 4. The reinforcement unit 4 provides a stable connection to the central frame 11. Then, the lifting rod 21 is activated, driving the fixing unit 3 upwards, thereby raising the central frame 11 to align with the isolation frame 1 that needs to be fixed. The connection between the central frame 11 and the isolation frame 1 is then welded and fixed. When the isolation net 12 needs to be fixed, it is placed in the gap between the central frame 11 and the isolation frame 1. The lifting rod 21 (an electric telescopic rod) is then inserted into the mesh of the isolation net 12. The fixing unit 3 and the reinforcement unit 4 are then activated to fix the isolation net 12. Finally, the lifting rod 21 is activated again. The isolation net 12 is moved upwards, aligning it with the central frame 11 and the isolation frame 1. Then, the isolation net 12 is welded and fixed in the gap between the central frame 11 and the isolation frame 1. A fixing unit 3 and a reinforcing unit 4 are provided. The fixing unit 3 is adjustable and mounted on the support box 2, providing a stable fixation to the bottom ends of the central frame 11 and the isolation net 12 that need to be welded to the isolation frame 1. The reinforcing unit 4 is located above the central frame 11 and the isolation net 12, fixing their top ends. This double fixing at both ends effectively prevents the central frame 11 and the isolation net from colliding during the welding process. The issues of displacement, swaying, warping, and deformation of the 12 frame are addressed, ensuring the accuracy of the welding position and the firmness of the welded joint. This greatly improves the welding quality of the police isolation net. By setting the fixing unit 3, it is possible to fix devices of different shapes, achieve stable fixing and welding of different workpieces, and meet the diverse production needs of the police isolation net. The lifting rod 21 set at the bottom of the support box 2 can easily adjust the installation height of the central frame 11 and the isolation net 12, making it easy to position the central frame 11 and the isolation net 12, improving the flexibility and efficiency of production, and meeting diverse production needs.

[0023] In one embodiment, the fixing unit 3 includes: a first screw 31, which passes through the inside of the support box 2; two lead screw sleeves 32, which are disposed on the first screw 31 and extend downward out of the support box 2, and the lead screw sleeves 32 are symmetrically arranged about the center of the first screw 31; two moving blocks 34, each moving block 34 being fixed to the lower part of a corresponding lead screw sleeve 32 and moving together with the lead screw sleeve 32; and support rods 35, which are spaced apart on the moving blocks 34 for supporting the bottom ends of the central frame 11 and the isolation net 12.

[0024] This design is for reference. Figure 3-5 The lead screw sleeves 32 are threadedly connected to the first screw 31 at intervals and symmetrically about the center of the support box 2. This symmetrical layout allows the moving block 34 to be evenly stressed during movement. When the moving block 34 drives the support rod 35 to support and fix the bottom of the central frame 11 and the isolation net 12, it ensures that the fixing force is evenly distributed at the bottom of the workpiece. When fixing the central frame 11, the lifting rod 21 is placed on the outside of the central frame 11, and then the installation position of the support box 2 is adjusted. The central frame 11 has a cross-shaped design. The moving block 34 is placed on the central frame 11. In the gap between them, the first screw 31 is rotated to drive the lead screw sleeve 32 to move inside the support box 2, so that the moving block 34 drives the support rod 35 to move closer to the cross center of the central frame 11. Then the lifting rod 21 is activated to drive the support rod 35 to move upward, so that the support rod 35 supports the bottom of the central frame 11. By controlling the rotation of the first screw 31, the lead screw sleeve 32 and the moving block 34 can be driven to make linear displacement, so that the support rod 35 can accurately reach the predetermined fixed position, thus meeting the fixing requirements of the central frame 11 and the isolation net 12 of different sizes.

[0025] In one embodiment, the first screw 31 is a bidirectional threaded rod with two one-way threads, and each one-way thread is provided with a lead screw sleeve 32. The helix directions of the two one-way threads are symmetrical about the center of the first screw 31, which is used to control the two lead screw sleeves 32 to move closer to each other or further away from each other.

[0026] This design is for reference. Figure 5 When welding the central frame 11 and the isolation net 12 of the police isolation net, it is necessary to fix them firmly. The design of the bidirectional threaded rod allows the operator to simply rotate the first screw 31, and the two screw sleeves 32 can move towards the side closer to the central frame 11. This can compress and fix the two sides of the central frame 11, thus ensuring a stable fixation of the central frame 11. After the central frame 11 is welded, the first screw 31 is rotated in the opposite direction, causing the two screw sleeves 32 to drive the support rod 35 to move away from each other, thereby canceling the fixation of the central frame 11. Then, the fixing unit 3 can be removed.

[0027] In one embodiment, the fixing unit 3 further includes a power mechanism 36, which is disposed on one side of the first screw 31 and is used to control the rotation of the first screw 31.

[0028] This design is for reference. Figure 1-6 The power mechanism 36 is installed on one side of the first screw 31 and is used to control the rotation of the first screw 31. By controlling the rotation angle of the first screw 31, the support rod 35 is controlled to support the bottom of the central frame 11 and the isolation net 12. The first screw 31 can be easily adjusted by setting the power mechanism 36.

[0029] In one embodiment, the power mechanism 36 includes: a rotating shaft 361 disposed on the support box 2; a first gear 362 sleeved on the rotating shaft 361; a handle 363 disposed on the rotating shaft 361 for driving the rotating shaft 361 to rotate; and a second gear 365 sleeved on the first screw 31 and meshing with the first gear 362 for transmitting kinetic energy to the first screw 31.

[0030] This design is for reference. Figure 4-6 The handle 363 is directly mounted on the rotating shaft 361. The operator can drive the rotating shaft 361 to rotate by turning the handle 363, thereby controlling the rotation of the first screw 31. The operator can flexibly control the force and speed of turning the handle 363 according to actual needs. When it is necessary to fine-tune the position of the support rod 35, the handle 363 can be turned slowly and gently to achieve precise displacement control; when it is necessary to make rapid adjustments, the force and speed of rotation can be increased to meet the operational requirements under different working conditions and enhance the flexibility of operation.

[0031] In one embodiment, the power mechanism 36 further includes: a locking member 364, disposed on the handle 363, for fixing the adjusted handle 363; the locking member 364 includes: a second screw 3641, threadedly connected to the handle 363; a turntable 3642, fixed on the side of the second screw 3641 away from the support box 2, for driving the second screw 3641 to make adjustments; and an abutment plate 3643, fixed on the side of the second screw 3641 close to the support box 2, for abutting and fixing with the support box 2.

[0032] This design is for reference. Figure 5 After adjusting the position of the support rod 35 and fixing the central frame 11 and the isolation net 12, the second screw 3641 is moved towards the support box 2 by rotating the turntable 3642, which drives the abutment plate 3643 to abut tightly against the support box 2. This keeps the positions of the first screw 31, the lead screw sleeve 32 and the support rod 35 fixed, ensuring that the workpiece is always in a stable fixed state and ensuring the welding quality.

[0033] In one embodiment, the support box 2 is provided with a moving groove 201 for moving the lead screw sleeve 32, and a guide rod 33 for guiding the lead screw sleeve 32 is provided inside the moving groove 201.

[0034] This design is for reference. Figure 4The moving groove 201 defines a clear path range for the movement of the lead screw sleeve 32, while the guide rod 33 further enhances this guiding role. When the first screw 31 rotates and drives the lead screw sleeve 32 to move, the guide rod 33 can ensure that the lead screw sleeve 32 moves smoothly along the predetermined straight direction, effectively avoiding the lead screw sleeve 32 from deviating, shaking or tilting during the movement, thereby ensuring the accuracy of the bottom support position of the central frame 11 and the isolation net 12, improving the precision of welding processing, enabling the welding points to be accurately connected, and improving product quality.

[0035] In one embodiment, the reinforcement unit 4 includes: a power component 41, disposed on the top of the support box 2, for driving the component to move up and down; a mounting frame 42, disposed at the power output end of the power component 41; a lifting plate 43, disposed at the lower end of the mounting frame 42; and a clamping plate 45, disposed at the lower end of the lifting plate 43, for pressing and fixing the top of the central frame 11 and the isolation net 12. The power component 41 includes, but is not limited to, a hydraulic cylinder, a linear guide rail, an electric push rod, and a pneumatic cylinder.

[0036] This design is for reference. Figure 1-4 ,as well as Figure 7-8 The power component 41 drives the mounting bracket 42, lifting plate 43, and clamping plate 45 to move downward as a whole, so that the clamping plate 45 can apply a uniform and stable extrusion force to the top of the central frame 11 and the isolation net 12. This top extrusion fixing method cooperates with the bottom support unit to form a stable structure with upper and lower clamping, which effectively prevents the central frame 11 and the isolation net 12 from displacement, shaking, or deformation caused by factors such as heat and vibration during the welding process, ensuring the accuracy of the welding point position and the consistency of welding quality, and improving the product qualification rate.

[0037] In one embodiment, the lifting plate 43 is symmetrically arranged about the support box 2.

[0038] This design is for reference. Figure 4 ,as well as Figure 7 The symmetrically arranged lifting plates 43 enable the clamping plates 45 to apply uniform compressive force to the top of the central frame 11 and the isolation net 12. When the power component 41 drives the lifting plates 43 to descend, the clamping plates 45 on both sides simultaneously apply the same magnitude and direction of force to the top of the workpiece, avoiding problems such as workpiece tilting, twisting or local deformation caused by unilateral force, ensuring that the central frame 11 and the isolation net 12 remain horizontal and stable during the welding process, and improving the reliability and effectiveness of fixing.

[0039] In one embodiment, guide frames 44 for guiding the lifting plate 43 are provided on both sides of the support box 2.

[0040] This design is for reference. Figure 4The guide frame 44 provides a precise linear track for the up and down movement of the lifting plate 43. When the power component 41 drives the lifting plate 43 to move, the guide frame 44 can restrict the lifting plate 43 to only make linear movements in the vertical direction, effectively preventing the lifting plate 43 from shifting, swaying or tilting in the horizontal direction. This allows the clamping plate 45 to accurately reach the predetermined position and precisely squeeze and fix the top of the central frame 11 and the isolation net 12, ensuring the accuracy of the welding point position.

The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
