When the clamping state of the quarantine fence is released, it is only necessary to start the electric push rod and remove the fence. The operation is convenient and can be quickly put into use in subsequent welding work, further improving the welding efficiency.

[0019] 3.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 11As shown, the present invention provides a technical solution: a welding tool for a quarantine fence for cattle and sheep livestock, comprising a frame assembly 1, an adjusting assembly 2 is arranged inside the frame assembly 1, a clamping assembly 3 is arranged on the top of the frame assembly 1, and a loosening assembly 4 is arranged on the bottom of the clamping assembly 3, the frame assembly 1 comprises a shell 101, a top plate 107 is fixedly connected to the top of the shell 101, the top plate 107 is provided with a plurality of second mounting grooves 108, and the plurality of second mounting grooves 108 are arranged in a criss-cross pattern, the adjusting assembly 2 comprises a first movable plate 201 and a second movable plate 205, the clamping assembly 3 comprises a first movable plate 201 and a second movable plate 205, and the clamping assembly 3 comprises a first movable plate 201 and a second movable plate 205. The number is set to be multiple, and the multiple clamping components 3 all include a connecting frame 310, and the top of the connecting frame 310 is symmetrically fixedly connected with a mounting frame 311 near the edges on both sides, and the outer surfaces of the two mounting frames 311 are symmetrically rotatably connected with a rotating shaft 313, the outer surfaces of the two rotating shafts 313 are fixedly connected with a gear shaft 314, the opposite ends of the two gear shafts 314 are fixedly connected with a connecting block 315, and the outer surfaces of the opposite sides of the two connecting blocks 315 are fixedly connected with an arc-shaped clamping plate 316, and the number of loosening components 4 is set to be multiple, and the multiple loosening components 4 all include a mounting plate 401.

[0035] The bottom of the connecting frame 310 is fixedly connected to the bottom shell 301, and the inner bottom center of the bottom shell 301 is fixedly connected to the limiting sleeve 306. The outer surface of the limiting sleeve 306 is slidably connected to a two-way ratchet bar 308, and the top of the two-way ratchet bar 308 is fixedly connected to a two-way rack 309. The top of the two-way rack 309 is fixedly connected to an arc-shaped supporting plate 312. The arc-shaped supporting plate 312 and the arc-shaped clamping plate 316 cooperate with each other, and the two-way rack 309 and the gear shaft 314 are meshed and connected. The connecting frame 310 is used to fix the bottom shell 301 and the mounting frame 311. The limiting sleeve 306 is used to limit the second spring 307 to prevent the second spring 307 from excessive bending and damage when it is compressed, and also plays a role in The two-way ratchet bar 308 has the function of moving and limiting. During the descent of the two-way rack 309, the two-way ratchet bar 308 at the bottom will be driven downward synchronously. During the downward movement of the two-way ratchet bar 308, the ratchet block 303 inside the bottom shell 301 will be squeezed away from the two-way ratchet bar 308. During this process, the first spring 304 will be squeezed and contracted by the ratchet block 303, and the second spring 307 will be squeezed and contracted by the two-way ratchet bar 308. When the two-way ratchet bar 308 moves to the lowest point following the two-way rack 309, the first spring 304 rebounds and squeezes the ratchet block 303 to press against the surface of the two-way ratchet bar 308, thereby forming a one-way meshing state, and thus preventing the two-way ratchet bar 308 from moving upward.

[0036] The second spring 307 is fixedly connected to the position inside the limiting sleeve 306 at the bottom of the bottom shell 301, and the top of the second spring 307 is fixedly connected to the inner top of the two-way ratchet bar 308. The outer surfaces of both sides of the bottom shell 301 are slidably connected to the third rails 318 near the bottom. The two third rails 318 are symmetrically fixedly connected between the inner walls of the second mounting groove 108. A connecting rod 317 is fixedly connected to the bottom center of the bottom shell 301. When the second spring 307 rebounds, the two-way ratchet bar 308 can be pushed upward to move up and reset. The third rails 318 are fixed in pairs inside the second mounting groove 108, and are used to limit the bottom shell 301 so that it can only move in a straight line along the second mounting groove 108. The connecting rod 317 is fixed at the bottom of the bottom shell 301 and can drive the bottom shell 301 to move when moving.

[0037] A ratchet block 303 is symmetrically and slidingly connected between the inner surface walls of the bottom shell 301, and limiting grooves 302 are symmetrically provided on the outer surfaces of the other two sides of the bottom shell 301. A limiting rod 305 is slidably connected between the inner surface walls of the limiting groove 302, and the limiting rod 305 and the ratchet block 303 are fixedly connected. A first spring 304 is fixedly connected between the outer surface of the ratchet block 303 and the inner surface wall of the bottom shell 301. The limiting groove 302 is used to limit the limiting rod 305, which indirectly plays a role in limiting the ratchet block 303, and the first spring 304 is mainly used to push the ratchet block 303 to fit tightly against the bidirectional ratchet bar 308.

[0038] The use steps of the present invention are as follows: the clamping assembly 3 in the device is mainly used to clamp the steel pipe fittings of the quarantine fence for cattle and sheep livestock. The steel pipe fittings are arranged in two directions, vertically and horizontally. The clamping assemblies 3 at corresponding positions have different orientations but the same usage. When in use, the steel pipe fittings of the quarantine fence are placed on the arc-shaped support plate 312 in the clamping assembly 3 as needed and arranged neatly. Then, the steel pipe fittings are pressed downward to move the arc-shaped support plate 312 downward. During the downward movement of the arc-shaped support plate 312, the two-way rack 309 at the bottom will follow the movement and drive the gear shafts 314 meshing with them on both sides to rotate in the direction of the arc-shaped support plate 312. The gear shaft 314 rotates through During the process, the arc clamping plate 316 will be driven to rotate synchronously through the connecting block 315. When the arc supporting plate 312 moves to the lowest point, it will form a circular clamp with the two arc supporting plates 312, so as to clamp the steel pipe fittings firmly. During the descending process of the two-way rack 309, the two-way ratchet bar 308 at the bottom will be driven to move downward synchronously. During the downward movement of the two-way ratchet bar 308, the ratchet block 303 inside the bottom shell 301 will be squeezed away from the two-way ratchet bar 308. During the process, the first spring 304 will be squeezed and contracted by the ratchet block 303, and the second spring 307 will be squeezed and contracted by the two-way ratchet bar 308. When the two-way ratchet bar 308 follows the two-way rack 309, the two-way ratchet bar 308 will move downward. When the first spring 304 is moved to the lowest point, the first spring 304 rebounds and squeezes the ratchet block 303 to fit closely to the surface of the two-way ratchet bar 308, thereby forming a one-way meshing state, which makes the two-way ratchet bar 308 unable to move up. At this time, the arc support plate 312 cooperates with the arc clamping plate 316 to keep the steel pipe fitting in a clamped state, which is convenient for subsequent welding operations. During the entire clamping and fixing process, the worker only needs to press down on the quarantine fence steel pipe fitting to be welded. The operation is simple and convenient, which effectively reduces the workload of the workers and improves the overall welding efficiency. According to actual conditions, the clamping surfaces of the arc support plate 312 and the arc clamping plate 316 can also be pasted with rubber pads to increase The friction force is increased while reducing friction damage. The bottom shell 301 is installed in the third track 318 inside the second installation groove 108, so it can move horizontally along the third track 318 but cannot move up and down. During the movement of the ratchet block 303, the limiting rod 305 on the surface will slide in the limiting groove 302, which has the effect of limiting the maximum movement stroke of the ratchet block 303. The limiting sleeve 306 is used to limit the second spring 307 to prevent excessive bending and damage of the second spring 307 when it is compressed. At the same time, it also plays a role in limiting the movement of the two-way ratchet bar 308. The connecting frame 310 is used to connect the mounting frame 311 and the bottom shell 301.

[0039] Embodiment 2: Figure 2-Figure 5As shown, the difference between the basis of the embodiment is that an electric push rod 109 is fixedly installed at the center of the bottom of the shell 101, and a lifting plate 105 is fixedly connected to the top of the electric push rod 109. The lifting plate 105 is located below the top plate 107 and the outer surface of the lifting plate 105 does not contact the inner wall of the shell 101. A plurality of first mounting grooves 106 are opened on the top of the lifting plate 105, and the positions of the first mounting grooves 106 and the second mounting grooves 108 correspond to each other. The electric push rod 109 is controlled by an external controller and can be electrically connected to an external power supply device through a connecting line. After the electric push rod 109 is started, it can drive the lifting plate 105 to move up and down, and a large number of mounting plates 401 are respectively installed in a large number of first mounting grooves 106.

[0040] An avoidance groove 402 is provided at the center of the top of the mounting plate 401, a slide plate 403 is slidably connected to the top of the mounting plate 401, a trapezoidal extrusion block 404 is symmetrically fixedly connected to the top of the slide plate 403 near the edge, an avoidance hole 405 is provided at the center of the top of the slide plate 403, the outer surface of the trapezoidal extrusion block 404 conflicts with the outer surface of the limit rod 305, the outer surface of the connecting rod 317 passes through the avoidance hole 405 and the avoidance groove 402, the mounting plate 401 is fixedly connected between the inner surface walls of the first mounting groove 106, the avoidance groove 402 is mainly used to avoid the connecting rod 317, so that the connecting rod 317 can drive the bottom shell 301 to move in a straight line along the first mounting groove 106 and the second mounting groove 108. The avoidance hole 405 is mainly used to avoid the connecting rod 317, so that the connecting rod 317 and the bottom shell 301 will not be squeezed when the slide plate 403 is lifted or lowered. The trapezoidal extrusion block 404 is initially located at the lowest point and will not limit the movement of the limit rod 305. When the electric push rod 109 pushes the lifting plate 105 to move upward, the inclined surface on the top of the trapezoidal extrusion block 404 will squeeze the corresponding two limit rods 305 away from each other, thereby driving the ratchet block 303 away from the two-way ratchet bar 308 through the limit rod 305.

[0041] The use steps of the present invention are as follows: when the steel pipe fittings need to be removed after being welded into a cattle and sheep livestock quarantine fence, the telescopic end of the electric push rod 109 is started to extend upward, and the lifting plate 105 will move upward at this time. During this process, the lifting plate 105 will drive the top slide plate 403 to move upward synchronously, and during the upward movement of the slide plate 403, the trapezoidal extrusion block 404 on its top will fit the surface of the bottom shell 301 and move upward. During this process, the two inclined surfaces on the top of the trapezoidal extrusion block 404 will gradually squeeze the two contacting limit rods 305 away from each other, thereby releasing the one-way meshing state of the ratchet block 303 and the bidirectional ratchet bar 308 inside the bottom shell 301. When the welded cattle and sheep livestock quarantine fence is taken down, due to the loss of weight on the arc-shaped support plate 312, the second spring 307 will rebound and push the two-way ratchet bar 308, the two-way rack 309 and the arc-shaped support plate 312 to move up and reset. During the resetting process of the two-way rack 309, the gear shaft 314 will be driven to rotate and reset, thereby making the two arc-shaped clamping plates 316 return to the open state. Finally, the electric push rod 109 can be controlled to retract and reset. When the clamping state of the quarantine fence is released, it is only necessary to start the electric push rod 109 and remove the fence. The operation is convenient and can be quickly put into use in subsequent welding work, further improving the welding efficiency.

[0042] Embodiment 3: Figure 1-Figure 7 , Fig.10 and Fig.11 As shown, the difference between the basis of the embodiment is that a first track 103 is symmetrically fixedly connected between the inner walls on two sides of the shell 101, and a second track 104 is symmetrically fixedly connected between the inner walls on the other two sides of the shell 101. The first track 103 is located below the second track 104, and universal wheels 102 are installed at the bottom of the shell 101 near the four corners. The first track 103 and the second track 104 are mainly used to install the first movable plate 201 and the second movable plate 205 inside the shell 101, and can move horizontally and linearly. The setting of the universal wheel 102 makes it easy to move the device, thereby adjusting the position of the device, improving the use effect and practicality.

[0043] The first movable plate 201 is slidably connected between the inner walls of the two first rails 103, and a first screw rod 203 is rotatably connected to the center of the outer surface of one side of the first movable plate 201. The outer surface thread of the first screw rod 203 penetrates the inner wall of the outer shell 101 and extends to the outside. The end of the first screw rod 203 away from the first movable plate 201 is fixedly connected to the first turning handle 204. The first turning handle 204 is mainly used to facilitate the rotation of the first screw rod 203. When the first screw rod 203 rotates, it will move linearly to the inside or outside of the outer shell 101 under the action of the thread, and at the same time drive the first movable plate 201 to move.

[0044] The second movable plate 205 is slidably connected between the inner walls of the two second rails 104, and a second screw rod 207 is rotatably connected at the center of the outer surface of one side of the second movable plate 205. The second screw rod 207 and the first screw rod 203 are vertically arranged. The outer surface thread of the second screw rod 207 penetrates the inner wall of the outer shell 101 and extends to the outside. The end of the second screw rod 207 away from the second movable plate 205 is fixedly connected with a second turning handle 208. The second turning handle 208 is mainly used to facilitate the rotation of the second screw rod 207. When the second screw rod 207 rotates, it will move linearly to the inside or outside of the outer shell 101 under the action of the thread, and at the same time drive the second movable plate 205 to move.

[0045] A group of first guide grooves 202 are fixedly connected to the top of the first movable plate 201, and the first guide grooves 202 are inclined. A plurality of groups of second guide grooves 206 are equidistantly provided on the top of the second movable plate 205, wherein the outer surfaces of several connecting rods 317 are slidably fitted with the inner surface walls of the first guide grooves 202, and the outer surfaces of several other connecting rods 317 are slidably fitted with the inner surface walls of the second guide grooves 206. A reserved groove is provided near the center of the first movable plate 201 and the second movable plate 205, and the reserved groove matches the position of the telescopic end of the electric push rod 109. The reserved grooves provided on the surfaces of the first movable plate 201 and the second movable plate 205 are mainly used to avoid the telescopic end of the electric push rod 109, and have a certain length, which can be After the second movable plate 205 moves and adjusts, it will not squeeze the telescopic end of the electric push rod 109. In addition to the second installation groove 108 and the reserved groove, the surface of the second movable plate 205 also has a through groove that avoids a part of the connecting rod 317 that needs to pass during the movement. The first guide grooves 202 are arranged in groups of two and are symmetrical. During the movement of the first movable plate 201, the first guide grooves 202 play a role in squeezing one part of the connecting rod 317, thereby prompting a part of the bottom shell 301 to move. The second guide grooves 206 are arranged in groups of two and are symmetrical. During the movement of the second movable plate 205, the second guide grooves 206 play a role in squeezing another part of the connecting rod 317, thereby prompting another part of the bottom shell 301 to move.

[0046] The use steps of the present invention are as follows: in actual use, the first screw rod 203 can be rotated by the first turning handle 204, at which time the first screw rod 203 will move toward the inside or outside of the housing 101, and drive the first movable plate 201 to move synchronously, and the bottom connecting rod 317 of the bottom shell 301 in the clamping assembly 3 for fixing the short steel pipe passes through the second movable plate 205 and is inserted into the first guide groove 202 on the surface of the first movable plate 201, and the connecting rod 317 is limited by the third track 318 on the inner side of the corresponding second mounting groove 108, so it is always at the intersection position of the second mounting groove 108 and the first guide groove 202. When the first guide groove 202 follows the movement of the first movable plate 201, the intersection position of the first guide groove 202 and the first guide groove 202 can be synchronously approached or moved away, so the distance between the short steel pipes can be adjusted, and when the second turning handle 208 is turned to drive the second screw rod 207 to rotate, the second movable plate 205 can be driven to move synchronously. During this process, since the bottom connecting rod 317 of the bottom shell 301 in the clamping assembly 3 for fixing the long steel pipe is inserted in the second guide groove 206, and each group of second guide grooves 206 is in an eight-shaped shape, the intersection of the movable second guide groove 206 and the corresponding second mounting groove 108 will be close to or far away, thereby playing a role in adjusting the spacing between the long steel pipes. Under mutual cooperation, the distance between the steel pipes to be welded of the quarantine fence can be adjusted, so as to position and clamp quarantine fences of different sizes, thereby increasing the practicality and use value of the device, and in the actual use of the device, the size of the frame assembly 1 and the adjustment assembly 2 can be adjusted according to the needs of use, and the number of the clamping assembly 3 and the loosening assembly 4 can be increased or multiple devices can be used in combination, so as to weld a large number of steel pipe fittings into a large-sized quarantine fence. It should be noted that when changing the use mode of the device, the first guide groove 202 on the surface of the first movable plate 201 should be designed to be diffused rather than simply increased in number.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
