Description

Technical Field

[0001] This utility model belongs to the field of safety fences, and in particular relates to a safety fence for a gantry welding machine. Background Technology

[0002] Gantry welding machines are a common type of welding equipment, typically used for batch production or large-scale welding operations. These machines are usually equipped with multiple welding heads, enabling welding at multiple locations simultaneously, thus improving production efficiency.

[0003] Chinese patent application number CN202320711662.4 discloses a safety fence, which is the main body of the device. It is a cuboid with a hollowed-out center and consists of fence legs, baffles, a left locking ring, wire mesh and a right locking ring. A sensing module is installed inside the fence frame and consists of a vibration detector, a vibration signal transmitter, a position detector, a position signal transmitter and a control module. A noise sensor is installed inside the fence frame. This invention overcomes the shortcomings of existing technologies. By setting up a sensing module, stabilizing piles, and connecting blocks, the sensing module can send the damage status and location to users when the fence is damaged, allowing users to take timely action and reduce losses. Users can also flexibly adjust the direction of the fence according to the construction scope, reducing the number of fences and the area enclosed by the fence, thus reducing inconvenience to surrounding residents. In contrast, the above-mentioned device connects individual fences more tightly by using chains through the left and right locking rings of two different fences. However, it requires aligning the left and right locking rings before using the chain to connect the two fences, making the operation more cumbersome.

[0004] Therefore, there is an urgent need to design a safety fence for gantry welding machines to solve the aforementioned problem of cumbersome operation. Utility Model Content

[0005] To address the technical problem of cumbersome operation mentioned in the background art, a safety fence for a gantry welding machine is provided to solve the problem of cumbersome operation.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a safety fence for a gantry welding machine is as follows:

[0007] A safety fence for a gantry welding machine includes a gantry welding machine body, a second safety fence frame, and a first safety fence frame. It includes a first fixing mechanism and a second fixing mechanism. The first fixing mechanism includes a connecting rod with a trapezoidal locking block installed at one end. L-shaped locking blocks are spaced apart on the inner wall of the gantry welding machine body, and the trapezoidal locking blocks can be inserted between the L-shaped locking blocks to install the second safety fence frame onto the gantry welding machine body. The second fixing mechanism includes a buckle installed on the first safety fence frame. Fixing blocks are installed on the inner wall of the second safety fence frame, and the fixing blocks cooperate with the buckle to achieve a locking connection between the second safety fence frame and the first safety fence frame.

[0008] Furthermore, the buckle is V-shaped, with two protrusions installed on it. A pull cord is connected to one side of the protrusions, and a pull ring is connected to the end of the pull cord away from the protrusions.

[0009] Furthermore, a guide tube is installed on the V-shaped buckle, and the pull rope is movably set inside the guide tube. The pull ring is made of rubber. Square grooves and circular grooves are opened on the outer wall of the first safety fence frame, and the square grooves and circular grooves are interconnected.

[0010] Furthermore, the first fixing mechanism also includes a throttle, which is located at the end of the connecting rod away from the trapezoidal locking block.

[0011] Furthermore, the first fixing mechanism also includes sleeves, two of which are installed on the inner wall of the gantry welding machine body respectively. A sliding rod is slidably connected to the sleeve, and an L-shaped locking block is installed at the end of the sliding rod away from the sleeve.

[0012] Furthermore, a spring is provided on the outer wall of the slide bar, and the spring is fixedly installed between the sleeve and the L-shaped locking block.

[0013] Furthermore, a fixing rod is installed on the outer circumference of the sleeve, and the end of the fixing rod away from the sleeve is fixedly installed on the inner wall of the gantry welding machine body.

[0014] Furthermore, each sleeve is fitted with two fixing rods, and the two fixing rods are symmetrically arranged with respect to the central axis of the sleeve.

[0015] Furthermore, both the second and first safety fence frames have grooves, and the first and second fixing mechanisms are respectively installed in the grooves.

[0016] Furthermore, the second safety fence frame and the first safety fence frame are equipped with multiple hinges, and multiple screws are connected to the hinges. Both the second safety fence frame and the first safety fence frame are hinged with protective plates.

[0017] The safety fence for the gantry welding machine of this utility model has the following advantages: The safety fence for the gantry welding machine fixes two second safety fence frames to the gantry welding machine body using a first fixing mechanism. When the first safety fence frame is brought close to the gantry welding machine body, its two trapezoidal blocks are first rotated clockwise so that the inclined surfaces on both sides face up and down respectively. Then, the buckle is aligned with the fixing block and pushed forward. Because the outer wall of the protrusion is arc-shaped, it can easily pass through the fixing block and be engaged on the other side of the fixing block. The buckle is fixedly connected to the first safety fence frame, and the fixing block is fixedly installed on the second safety fence frame. At this time, when stationary, the distance between the two L-shaped blocks is greater than the width of the vertical trapezoidal block, and the trapezoidal block can smoothly enter the inside of the L-shaped block. Then, the handle is rotated 90 degrees to make the trapezoidal block horizontal. At this time, its width is greater than the channel between the L-shaped blocks, and the L-shaped block can lock the trapezoidal block. The first safety fence frame can then be fixed to the gantry welding machine body. The second fixing mechanism can conveniently connect the first and second safety fence frames to prevent loosening.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0030] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This utility model describes a safety fence for a gantry welding machine.

[0031] This embodiment provides a safety fence for a gantry welding machine, such as Figures 1-5 As shown, the safety fence for the gantry welding machine includes a gantry welding machine body 1, a second safety fence frame 4, and a first safety fence frame 12. It includes a first fixing mechanism 2 and a second fixing mechanism 3. The first fixing mechanism 2 includes a connecting rod 202, one end of which is equipped with a trapezoidal locking block 203. The inner wall of the gantry welding machine body 1 is provided with L-shaped locking blocks 207 at intervals. The trapezoidal locking blocks 203 can be inserted between the L-shaped locking blocks 207 to install the second safety fence frame 4 on the gantry welding machine body 1. The second fixing mechanism 3 includes a buckle, which is installed on the first safety fence frame 12. The inner wall of the second safety fence frame 4 is equipped with a fixing block 303, which is used to cooperate with the buckle to realize the snap-fit ​​between the second safety fence frame 4 and the first safety fence frame 12.

[0032] Specifically, the trapezoidal locking block 203 can rotate relative to the L-shaped locking block 207. During installation, the two second safety fence frames 4 are fixed to the gantry welding machine body 1 by the first fixing mechanism 2. First, rotate the two trapezoidal locking blocks 203 on the first safety fence frame 12 clockwise by 90 degrees, that is, the inclined surfaces on both sides of the trapezoidal locking block 203 face up and down respectively. At this time, align the V-shaped buckle 301 on the first safety fence frame 12 with the direction of the fixing block 303 and push it towards the direction of the fixing block 303. This is to bring the first safety fence frame 12 closer to the edge of the gantry welding machine body 1, because the outer wall of the protrusion 302 is arc-shaped. Because the protrusion 302 can easily pass through the fixing block 303 and engage with the other side of the fixing block 303, when the L-shaped block 207 is stationary, the distance between the two L-shaped blocks 207 is greater than the vertical width of the trapezoidal block 203. Therefore, the trapezoidal block 203 can pass well to the inside of the L-shaped block 207. By rotating the handle 201 on the two first safety fence frames 12 ninety degrees, the trapezoidal block 203 is adjusted to a horizontal state. At this time, the width of the horizontal trapezoidal block 203 is greater than the channel between the two L-shaped blocks 207, and the L-shaped block 207 can engage the trapezoidal block 203 well. The second fixing mechanism 3 can conveniently and quickly connect the second safety fence frame 4 and the first safety fence frame 12, and prevent them from loosening when they are fixed together.

[0033] Furthermore, as a preferred embodiment, such as Figure 4 and Figure 5 As shown, the buckle is V-shaped, and two protrusions 302 are installed on the V-shaped buckle 301. A pull rope 305 is connected to one side of the protrusion 302, and a pull ring 304 is connected to the end of the pull rope 305 away from the protrusion 302.

[0034] Specifically, a guide tube 11 is installed on the V-shaped buckle 301, the pull rope 305 is movably set inside the guide tube 11, the pull ring 304 is made of rubber, and a square groove 6 and a circular groove 7 are opened on the outer wall of the first safety fence frame 12, and the square groove 6 and the circular groove 7 are interconnected.

[0035] The guide tube 11 provides a clear path and guidance for the pull rope 305, ensuring that the pull rope 305 does not deviate from its direction or be interfered with by external obstacles during movement. At the same time, the guide tube 11 also protects the pull rope 305, extending its service life. The pull ring 304 is made of rubber, a soft and comfortable material that is easy for users to grip. When not in use, the pull rope 305 and pull ring 304 can be stored inside the square groove 6 and circular groove 7. The friction between the pull ring 304 and the inner wall of the circular groove 7 prevents it from easily falling off.

[0036] Furthermore, the first fixing mechanism 2 also includes a throttle 201, which is located at the end of the connecting rod 202 away from the trapezoidal locking block 203.

[0037] It should be noted that both the second safety fence frame 4 and the first safety fence frame 12 have a handle 201, a connecting rod 202, and a trapezoidal locking block 203. The second safety fence frame 4 is fitted onto the connecting rod 202, and the handle 201 and the trapezoidal locking block 203 are respectively located on both sides of the second safety fence frame 4. The first safety fence frame 12 is the same.

[0038] Furthermore, such as Figure 3 As shown, the first fixing mechanism 2 also includes a sleeve 204. There are two sleeves 204, which are respectively installed on the inner wall of the gantry welding machine body 1. A slide rod 205 is slidably connected to the sleeve 204. An L-shaped locking block 207 is installed at the end of the slide rod 205 away from the sleeve 204.

[0039] Specifically, a spring 206 is provided on the outer wall of the slide bar 205, and the spring 206 is fixedly installed between the sleeve 204 and the L-shaped locking block 207.

[0040] During installation, the second safety fence frame 4 is first attached to one side of the gantry welding machine body 1. The operator rotates the handle 201 so that the inclined surfaces on both sides of the trapezoidal block 203 correspond to the inclined surfaces of the L-shaped block 207. The connecting rod 202 is then pushed towards the gantry welding machine body 1. The connecting rod 202 pushes the trapezoidal block 203 towards the inner side of the L-shaped block 207. At this time, the L-shaped block 207 is squeezed by the trapezoidal block 203 and moves synchronously to both sides. The spring 206 is fixedly connected to the L-shaped block 207. The spring 206 is compressed by force, and at the same time, the sliding rod 205 slides into the sleeve 204, so that the protrusion of the L-shaped block 207 locks the trapezoidal block 203. The first fixing mechanism 2 can install the second safety fence frame 4 and the first safety fence frame 12 around the gantry welding machine body 1, and is also easy to disassemble.

[0041] Furthermore, such as Figure 3 As shown, a fixing rod 5 is installed on the outer circumference of the sleeve 204, and the end of the fixing rod 5 away from the sleeve 204 is fixedly installed on the inner wall of the gantry welding machine body 1.

[0042] Specifically, such as Figure 3 As shown, each sleeve 204 is equipped with two fixing rods 5, and the two fixing rods 5 are symmetrically arranged with respect to the central axis of the sleeve 204. The symmetrical arrangement of the fixing rods 5 makes the position of the sleeve 204 inside the gantry welding machine body 1 more stable. This symmetrical structure reduces vibration or movement caused by imbalance or eccentricity, thereby improving the stability of the overall structure. By using symmetrical fixing rods 5, not only is the number of fixed parts reduced, but manufacturing and maintenance costs are also lowered.

[0043] Furthermore, such as Figure 1 and Figure 4 As shown, both the second safety fence frame 4 and the first safety fence frame 12 have grooves 14, and the first fixing mechanism 2 and the second fixing mechanism 3 are respectively set in the grooves 14.

[0044] Furthermore, such as Figure 4 As shown, multiple hinges 8 are installed on the second safety fence frame 4 and the first safety fence frame 12, and multiple screws 9 are connected to the hinges 8. Both the second safety fence frame 4 and the first safety fence frame 12 are hinged to protective plates 10 through the hinges 8.

[0045] The protective plate 10, hinged by hinge 8, can be adjusted in angle to adapt to different working environments and protection requirements. The screws 9 provide a stable connection for hinge 8, ensuring a stable connection between the second safety fence frame 4, the first safety fence frame 12, and the protective plate 10. The protective plate 10 effectively protects the handle 201, preventing external people or other objects from colliding with it and causing it to move other structures, thus compromising the stability of the first fixing mechanism 2. The groove 14 also serves to protect the handle 201.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, the protective plate 10 is set on one side of the throttle 201. Two magnets 13 are installed on both the second safety fence frame 4 and the first safety fence frame 12. The protective plate 10 is made of iron and is attached to the magnets 13.

[0047] Since the protective plate 10 is made of iron, it can be magnetically attracted to the magnet 13. The side of the protective plate 10 away from the hinge 8 is fixed to the outer wall of the second safety fence frame 4 and the first safety fence frame 12 by the magnet 13, thus achieving the purpose of protecting the handle 201. The magnetic attraction of the magnet 13 ensures that the protective plate 10 will not move arbitrarily when not needed.

[0048] The working principle of the safety fence for the gantry welding machine is as follows: Two second safety fence frames 4 are fixed to the gantry welding machine body 1 via the first fixing mechanism 2. First, the two trapezoidal blocks 203 on the first safety fence frame 12 are rotated 90 degrees clockwise, meaning the inclined surfaces on both sides of the trapezoidal blocks 203 face upwards and downwards respectively. Then, the V-shaped buckles 301 on the first safety fence frame 12 are aligned with the fixing blocks 303 and pushed towards them. Because the outer wall of the protrusion 302 is arc-shaped, the protrusion 302 can pass through relatively easily. The second fixing mechanism 3 engages with the other side of the fixing block 303. When the L-shaped blocks 207 are stationary, the distance between the two L-shaped blocks 207 is greater than the vertical width of the trapezoidal block 203. Therefore, the trapezoidal block 203 can pass well to the inside of the L-shaped blocks 207. Rotating the handles 201 on the two first safety fence frames 12 by ninety degrees adjusts the trapezoidal block 203 to a horizontal position. At this point, the width of the horizontal trapezoidal block 203 is greater than the passage between the two L-shaped blocks 207, allowing the L-shaped blocks 207 to effectively engage the trapezoidal block 203. The second fixing mechanism 3 can conveniently and quickly connect the second safety fence frame 4 and the first safety fence frame 12, preventing them from loosening when fixed together.

[0049] First, attach the second safety fence frame 4 to one side of the gantry welding machine body 1. The operator rotates the handle 201 so that the inclined surfaces on both sides of the trapezoidal block 203 correspond to the inclined surfaces of the L-shaped block 207. The connecting rod 202 is then pushed towards the gantry welding machine body 1. The connecting rod 202 pushes the trapezoidal block 203 towards the inner side of the L-shaped block 207. At this time, the L-shaped block 207 is squeezed by the trapezoidal block 203 and moves synchronously to both sides. The spring 206 is fixedly connected to the L-shaped block 207. The spring 206 is compressed by force, and at the same time, the sliding rod 205 slides into the sleeve 204, so that the protrusion of the L-shaped block 207 locks the trapezoidal block 203. The first fixing mechanism 2 can install the second safety fence frame 4 and the first safety fence frame 12 around the gantry welding machine body 1, and is also easy to disassemble.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
