[0037] Figure 1 A schematic diagram of an embodiment of the present invention is shown, specifically illustrating the structure of this embodiment. This embodiment relates to a device for quick connection and fastening of socket-type pipes. The socket-type pipe and the connecting pipe are clamped by at least one clamping device. An adjusting device can adjust the connection height. After adjustment, the clamping device is moved by the adjusting device to connect the pipes. The device of this embodiment can effectively reduce the investment of large machinery, reduce the number of auxiliary operators, reduce labor and machinery costs, and improve work efficiency when connecting and fastening pipes.

[0038] A method for fastening socket-type pipe connections, comprising the following steps:

[0039] A connecting device is provided at one end of the adjusting device, and the connecting device is detachably connected to the adjusting device.

[0040] A clamping device is provided on the same side as the adjusting device and the connecting device;

[0041] Adjust the clamping device to bring it to the same horizontal position;

[0042] Install the socket-type pipes into the clamping device respectively;

[0043] The adjusting device is used to move the clamping device to connect the socket-type pipes.

[0044] A device for fastening socket-type pipe connections, such as Figure 1-6 As shown, the device includes an adjustment device, a clamping device, and a connecting device. In this embodiment, the adjustment device includes a guide box 1, a locking block 2, a hand crank arm a3, a rack 4, a gear 5, and a connecting rod 6. The guide box 1 is a rectangular hollow block that fits around the outside of the rack 4. The gear 5 is located inside the guide box 1 and on the rack 4, and can move along the rack 4. A hand crank arm a3 is located on the outside of the guide box 1. The hand crank arm a3 passes through the guide box 1 and connects to the gear 5 located inside the guide box 1. By manually rotating the hand crank arm a3, the gear 5 can be moved on the rack 4. Figure 3 As shown, a locking block 2 is provided between the hand crank arm a3 and the gear 4. The locking block 2 can rotate along the connecting rod of the hand crank arm a3. One end of the locking block 2 is parallel to the tooth of the rack 4, which can restrict the movement of the gear 5. In some feasible embodiments, the hand crank arm a3 is set as an electric drive shaft, including a motor and a transmission shaft. The motor can drive the transmission shaft to rotate, which drives the gear 5 to rotate and move the guide box 1 on the rack 4. The speed of the motor can be set and the speed of the gear 5 can be adjusted. This method can greatly improve the construction efficiency. Scale lines are provided on both sides of the rack 4. The movement distance can be recorded through the scale lines to realize the accurate measurement of the insertion length required for different socket pipes and improve the accuracy of the connection.

[0045] The clamping device includes a guide box 1, a locking block 2, a hand crank arm b9, a rack 4, a gear 5, a clamping plate 7, and an adjustable clamping piece 10. The connecting rod 6 is connected to the I-beam of the clamping device. A rack 4 is provided on the top of one side of the I-beam, and the guide box 1 is installed on the rack 4. The gear 5 and the locking block 2 are installed inside the guide box 1, and the hand crank arm b9 is connected to the outside. The connecting rod 6 is installed at the bottom of the guide box 1. A fixing rod is provided on the other side of the I-beam, which is parallel to the connecting rod 6. A clamping plate 7 is provided on the opposite side of the connecting rod 6 and the fixing rod. In this embodiment, the clamping plate 7 is set in a curved shape and is connected to the rod body through the adjustable clamping piece 10. The bending angle of the clamping plate 7 is adjusted by widening the connection gap between the clamping plates 7. A countersunk bolt 8 is provided on the other side of the rod body. The countersunk bolt 8 is connected to the adjustable clamping piece 10 to fix the clamping plate 7 after adjustment.

[0046] The connecting device includes a connecting component 11, a connecting block 12, a pin 13, a rivet 14, a sliding lock box 15, and a pin hole 16. One end of the rod of the connecting device is provided with a placement groove, and one end of the rack 4 is also provided with a placement groove for placing the connecting block 12. A hole is provided on the outside of the rod for fixing the connecting block 12 by placing the rivet 14. At the same time, pins 13 are provided on opposite sides of the plate of the connecting block 12 for connecting and fixing the rack 4 and the rod of the connecting device in conjunction with the sliding lock box 15.

[0047] The socket-type pipe quick connection and fastening device mainly consists of a rack, gear, guide box / gear protective cover, locking block, hand crank arm, and pipe clamp. The rack, gear, guide box / gear protective cover, locking block, and hand crank arm form the main frame structure of this tool, used to move two pipe sections in opposite directions to ensure a tight connection between their pipe ends. The rack, gear, guide box / gear protective cover, locking block, hand crank arm, and pipe clamp form two sets of adjustable pipe section fixers that can be adjusted according to the pipe size, used to fix the two pipe sections.

[0048] The rack and adjustable retainer rod of the connecting pipe section constitute the fixed end of the tool; the gear, guide box / gear cover, locking block, hand crank arm, and adjustable retainer of the connecting pipe section constitute the movable end of the tool.

[0049] Two sets of adjustable pipe section clamps are welded to the main frame structure of the tool, one set is connected to the fixed end part and the other set is connected to the movable end part; similarly, two sets of adjustable pipe section clamps are bolted to the fixed end part and the movable end part directly below.

[0050] The adjustable clamps for pipe sections are made of high-strength steel. The steel is grooved along the centerline, with the groove width being 4mm larger than the bolt diameter. This allows for easy adjustment of the clamp size according to the pipe section diameter. A rubber plate is installed on the inner side of the contact surface with the pipe via rivets. This rubber plate is 5mm wider than the steel clamps on both sides to enhance friction with the pipe and effectively prevent rigid contact between the clamp and the pipe wall, which could cause damage to the pipe wall.

[0051] The rack has markings on both sides to facilitate control of the insertion depth and applied force of the socket, preventing damage to the pipe opening and inner wall caused by excessive force or excessive insertion, resulting in poor joint sealing.

[0052] This embodiment describes in detail the connection method of socket-type pipes, including the following steps:

[0053] Step 1: Adjust the opening of this adjustable pipe section fixing device according to the diameter of the pipe to be laid, using hand crank a3 and hand crank b9 to place it at both ends and above the pipe interface.

[0054] Step 2: Adjust the adjustable clamp 10 and clamping plate 7 of the pipe section adjustable fixing device according to the diameter of the pipe to be laid so that they can be placed on both sides of the pipe.

[0055] Step 3: After placing the device completely on the pipe, first adjust the adjustable clamp 10 and clamping plate 7 of the pipe section adjustable fixing device to clamp the pipe according to the diameter of the pipe to be laid. Then, adjust the opening of the pipe section adjustable fixing device by hand cranking arm b9 until the tool no longer falls down.

[0056] Step 4: Before laying the pipe, measure the length of the pipe opening that extends into the pipe and mark the maximum extension line at the pipe opening with a marker.

[0057] Step 5: Start tightening the two pipe sections by rotating the hand crank a3, and pay attention to the scale on both sides of the rack 4 to control the speed and force of the hand crank a3 rotation. Tighten until the marked line is reached and the corresponding scale is measured. The tightening is then considered complete.

[0058] Step 6: To accommodate various angles and directions of pipe docking and fastening scenarios, the fixed end and the movable end are connected to both sides of the connecting block 12 in the connecting component 11 with rivets 14 to form the overall structure of the device.

[0059] Step 7: During use, the vertical or horizontal rotation end can be locked by sliding the locking box 15 to ensure that the overall device always meets the required angle. The unlocked end can meet the application scenarios, such as horizontal direction, horizontal direction perpendicular to vertical direction, or two pipes at any angle.

[0060] Step 8: When it is necessary to lock the vertical or horizontal rotation, the sliding lock box 15 can be moved left or right to lock it. When the sliding lock box is moved to the point where the locking hole 16 of the sliding lock box coincides with the locking hole on the connecting block, the pin 13 is used to lock it in place. This ensures that the sliding lock box 15 will not move or be misaligned, which would prevent the locking purpose from being achieved.

[0061] The advantages and positive effects of this invention are as follows: By adopting the above-mentioned technical solution, the investment of large machinery is effectively reduced during pipe connection and fastening, the number of auxiliary operators is reduced, and labor and machinery costs are lowered, while also improving worker efficiency; the maximum depth of the pipe section can be controlled by the scale markings on the tool, which can effectively control the applied force and prevent excessive force from causing damage to the pipe end and socket, greatly reducing material breakage rate, reducing material waste, and lowering material costs; it improves the sealing performance of the interface and improves the installation quality; it is reusable and requires a small initial investment.

[0062] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
