Description

Technical Field

[0001] The invention relates to the technical field of tunnel waterproof construction, in particular to an automatic welding device with an adaptive electromagnetic welding gun used for laying and welding waterproof boards. Background Art

[0002] During the tunnel waterproofing construction process, after the geotextile buffer layer is laid and anchored, a waterproof board needs to be laid on its surface, and the laid waterproof board is fixed to the hot-melt liner anchored on the geotextile surface using welding or bonding technology. The welding strength is required to be high and there should be no defects such as leaking welds, cold welds or melt-through.

[0003] At present, most tunnel waterproofing board welding is carried out manually. After the worker locates the welding position, he holds the electromagnetic welding gun and presses the flat surface of one end of the gun head completely against the waterproofing board and presses it against the hot melt pad behind it. Then he starts the electromagnetic welding gun to weld the waterproofing board to the surface of the hot melt pad.

[0004] The manual welding method of tunnel waterproofing panels on hot-melt linings is simple to operate and requires high worker proficiency. However, with the improvement of the automation level of tunnel construction equipment, waterproofing panel welding also needs to form automated process technology and be combined with automated construction trolleys to form fully automatic equipment for tunnel waterproofing construction. In the actual implementation of automated welding, due to the inevitable uneven protrusions or depressions on the initial support base of the tunnel, the hot-melt lining often tilts and deflects after being fixed on the support surface when the geotextile is laid and fixed, resulting in problems such as cold welding during machine welding. Summary of the Invention

[0005] In response to the above-mentioned problems, the present invention proposes an adaptive automatic electromagnetic welding device for waterproof boards, which realizes fully automatic welding of the waterproof boards by an automatic trolley after the waterproof boards are laid, and can automatically adapt to the irregular posture of the welding object caused by uneven supporting surfaces.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An adaptive automatic electromagnetic welding device for waterproof panels comprises a welding platform, an adaptive welding mechanism, and a base panel; the welding platform is mounted on the base panel and comprises a cylinder seat, a driving cylinder, a floating joint, a support plate, a linear guide pair, and a slide box; the support plate is vertically mounted on the base panel, a linear guide pair is assembled on the support plate, and a slider of the linear guide pair is connected to the side wall of the slide box; the cylinder seat is fixedly mounted on the base panel, the driving cylinder is vertically mounted on the cylinder seat, the floating joint is mounted on the end of the actuating rod of the driving cylinder and is connected to the slide box, and the driving cylinder can drive the slide box to move vertically up and down along the linear guide pair on the support plate;

[0008] The adaptive welding mechanism is installed on the slide box, and includes a posture self-adjusting fixed ring, a posture self-adjusting floating ring, a welding gun locking component A, a welding gun locking component B, a longitudinal pin shaft, a transverse pin shaft, a tension spring mechanism and a welding gun;

[0009] The posture self-adjusting fixed ring is fixedly installed on the sliding box, the posture self-adjusting fixed ring is a rectangular frame structure, the posture self-adjusting floating ring is also a rectangular frame structure, and the posture self-adjusting floating ring is located on the inner side of the posture self-adjusting fixed ring, and is connected to the posture self-adjusting fixed ring through two symmetrical transverse pin shafts; the welding gun locking component A and the welding gun locking component B are assembled into an inner frame by bolts to clamp the welding gun in the center; the inner frame assembled by the welding gun locking component A and the welding gun locking component B is located on the inner side of the posture self-adjusting floating ring, and is connected to the posture self-adjusting floating ring through two symmetrical longitudinal pin shafts; a tension spring mechanism is provided between the inner frame and the posture self-adjusting floating ring, and a tension spring mechanism is also provided between the posture self-adjusting floating ring and the posture self-adjusting fixed ring.

[0010] In the above technical solution, there are two support plates, which are located on both sides of the sliding box.

[0011] In the above technical solution, the tops of the two support plates are connected by a support plate connecting plate.

[0012] In the above technical solution, the base panel is located at the lowest end of the entire device and is used to be connected to the automatic trolley for tunnel construction.

[0013] In the above technical solution, four tension spring mechanisms are arranged between the inner frame and the posture self-adjusting floating ring. The four tension spring mechanisms are arranged as follows: one tension spring mechanism is arranged on each side of each longitudinal pin shaft.

[0014] In the above technical solution, four tension spring mechanisms are arranged between the posture self-adjusting floating ring and the posture self-adjusting fixed ring. The four tension spring mechanisms are arranged as follows: one tension spring mechanism is arranged on each side of each transverse pin shaft.

[0015] The working method of the self-adaptive waterproof board automatic electromagnetic welding device is as follows:

[0016] First, under the control of the control system, the driving cylinder is started, and the slide box is driven by the floating joint to perform welding feed action along the linear guide pair on the support plate and reach the designed stroke, so that the front welding part of the welding gun fixed on the adaptive welding mechanism contacts the waterproof plate and the hot melt gasket;

[0017] When the hot melt backing presents an irregular posture due to the uneven support surface, under the action of the driving cylinder on the front pressure of the welding gun, the welding gun will drive the inner frame and the posture self-adjusting floating ring to adjust the posture in a controlled manner under the damping provided by the tension spring mechanism to adapt to the welding working surface;

[0018] Afterwards, the control system controls the welding gun to heat the hot melt gasket and waterproof board at a constant temperature;

[0021] 1. The rigid fixation of the welding gun in general devices is changed to a three-level connection fixation based on the gyroscope principle, so that the welding gun can have two degrees of freedom of swing along the X-axis and Y-axis in space, so that the welding gun can adapt to uneven welding environments.

[0022] 2. A spring connection is set between the posture self-adjusting fixed ring, the posture self-adjusting floating ring and the clamping component to provide damping for the two-degree-of-freedom spatial swing of the welding gun, ensuring that it is in a perpendicular state to the welding surface in normal posture.

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below.

[0031] The present invention proposes an adaptive automatic electromagnetic welding device for waterproof boards, as shown in the figure, comprising a welding platform 1, an adaptive welding mechanism 2 and a base panel 3. The base panel 3 is located at the bottom of the overall device and can be connected to an automatic trolley for tunnel construction. The welding platform 1 is installed on the base panel 3 and forms a semi-enclosure for the adaptive welding mechanism 2 installed thereon.

[0032] The welding platform 1 is installed on the base panel 3 and includes a cylinder base 101, a driving cylinder 102, a floating joint 103, a support plate 104, a linear guide pair 105, a slide box 106 and a support plate connecting plate 107.

[0033] Specifically, the support plates 104 are vertically mounted on the base panel 3. There are two support plates 104, located on both sides of the slide box 106. A linear guide pair 105 is mounted on the support plates 104. The sliders of the linear guide pair 105 are connected to the side walls of the slide box 106, thereby providing a guide for the slide box 106 to be welded and fed. To ensure the relative assembly position accuracy of the linear guide pair, a support plate connecting plate 107 is used to precisely position and connect the two support plates 104 from the top. The cylinder base 101 is fixedly mounted on the base panel 3. The driving cylinder 102 is vertically mounted on the cylinder base 101. The actuating rod of the driving cylinder 102 is set downward. The floating joint 103 is mounted on the end of the actuating rod of the driving cylinder 102 and is connected to the slide box 106. The driving cylinder 102 can then drive the slide box 106 to move vertically up and down along the linear guide pair 105 on the support plate 104.

[0034] The adaptive welding mechanism 2 is installed on the slide box 106, and includes a posture self-adjusting fixed ring 201, a posture self-adjusting floating ring 202, a welding gun locking component A203, a welding gun locking component B204, a longitudinal pin 205, a transverse pin 206, a tension spring mechanism 207 and a welding gun 210.

[0035] Specifically, the posture self-adjusting fixed ring 201 is fixedly installed on the sliding box 106, and the posture self-adjusting fixed ring 201 is a rectangular frame structure (the front end of the posture self-adjusting fixed ring 201 is connected to the fixed ring end cover 208), and the posture self-adjusting floating ring 202 is also a rectangular frame structure (the front end of the posture self-adjusting floating ring 202 is connected to the floating ring cover 209), and the posture self-adjusting floating ring 202 is located on the inner side of the posture self-adjusting fixed ring 201, and is connected to the posture self-adjusting fixed ring 201 through two symmetrical transverse pins 206, so that the posture self-adjusting floating ring 202 can rotate transversely. The pin shaft 206 rotates relative to the posture self-adjusting fixing ring 201, producing a floating effect; the welding gun locking component A203 and the welding gun locking component B204 are assembled into an inner frame by bolts, clamping the welding gun 210 in the center; the inner frame assembled by the welding gun locking component A203 and the welding gun locking component B204 is located on the inner side of the posture self-adjusting floating ring 202, and is connected to the posture self-adjusting floating ring 202 through two symmetrical longitudinal pin shafts 205, and then the inner frame can rotate relative to the posture self-adjusting floating ring 202 around the longitudinal pin shaft 205, thereby producing a floating effect.

[0036] Four tension spring mechanisms 207 are arranged between the inner frame and the posture self-adjusting floating ring 202 (the first end of each tension spring mechanism is connected to the inner frame, and the other end is connected to the posture self-adjusting floating ring) to enable the inner frame and the posture self-adjusting floating ring 202 to have an adaptive adjustment function; further, the arrangement of these four tension spring mechanisms 207 is: one tension spring mechanism 207 is arranged on both sides of each longitudinal pin shaft 205.

[0037] Four tension spring mechanisms 207 are also arranged between the posture self-adjusting floating ring 202 and the posture self-adjusting fixed ring 201 (the first end of each tension spring mechanism is connected to the posture self-adjusting floating ring, and the other end is connected to the posture self-adjusting fixed ring) to enable the posture self-adjusting floating ring 202 and the posture self-adjusting fixed ring 201 to have an adaptive adjustment function; further, the arrangement of these four tension spring mechanisms 207 is: one tension spring mechanism 207 is arranged on each side of each transverse pin shaft 206.

[0038] The working method of the self-adaptive waterproof board automatic electromagnetic welding device is as follows:

[0039] First, under the action of the control system, the driving cylinder 102 is started, and the slide box 106 is driven through the floating joint 103 to perform welding feed action along the linear guide pair 105 on the support plate 104 and reach the designed stroke, so that the front welding part of the welding gun 210 fixed on the adaptive welding mechanism 2 contacts the waterproof board and the hot melt pad.

[0040] When the hot melt pad presents an irregular posture due to the uneven supporting surface, under the action of the driving cylinder 102 on the front pressure of the welding gun, the welding gun 210 will drive the inner frame and the posture self-adjusting floating ring 202 to undergo a controlled posture adjustment under the damping provided by the tension spring mechanism 207 to adapt to the welding work surface.

[0041] Afterwards, the control system controls the welding gun 210 to operate and heat the hot melt gasket and the waterproof board at a constant temperature.

[0042] Finally, the driving cylinder 102 is controlled to retract, and a working process is completed.

[0043] It should be understood that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
