Description

Technical Field

[0001] This utility model relates to the field of waterproof construction welding technology, specifically to a hot wedge welding device for waterproof construction of evaporation ponds. Background Technology

[0002] Hot wedge welding equipment is a high-efficiency device for welding thermoplastic materials. It melts the material using an electrically heated wedge-shaped metal head, and then applies pressure rollers to bond it. It employs a PID temperature control system suitable for materials such as PE, PP, and PVC, and supports continuous operation. Adjustable pressure ensures the weld strength reaches over 90% of the base material, with no burrs and excellent airtightness. It is widely used in industrial fields such as waterproof membranes, geomembranes, and tarpaulins, and is particularly suitable for applications requiring high-strength linear seals, such as environmental engineering and building waterproofing. Traditional hot wedge welding equipment often has a wheeled bottom structure. Due to the relatively uneven surface of evaporation ponds and the angle at the slope location, traditional wheeled hot wedge welding equipment can experience jamming of the walking mechanism during operation, affecting the quality of waterproofing construction. Utility Model Content

[0003] The purpose of this utility model is to provide a hot wedge welding device for waterproofing construction of evaporation ponds, in order to solve the problem mentioned in the background art that the bottom of the traditional hot wedge welding device is mostly a wheel structure. Due to the relatively low flatness of the evaporation pond ground and the angle at the slope position, the traditional wheel structure hot wedge welding device has a problem of the walking mechanism getting stuck during operation, which affects the quality of waterproofing construction.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hot wedge welding device for waterproofing construction of evaporation ponds, comprising a walking frame, a machine body located on the upper side of one side of the walking frame, a support frame located inside the other side of the walking frame, a clamping frame rotatably connected inside the machine body via a rotating shaft, the clamping frame correspondingly arranged with the support frame, support rollers rotatably connected inside both the support frame and the clamping frame via rotating shafts, a welding hot wedge located inside the clamping frame and between the upper and lower support rollers, a support track located on one side of the lower surface of the walking frame and below the support frame, a guide wheel located on the other side of the lower surface of the walking frame, and clamping wheels correspondingly located inside the walking frame and outside the support frame and the clamping frame.

[0005] Preferably, the walking frame is a C-shaped structure consisting of a metal square tube profile and metal circular profiles at both ends. The clamping wheel at the lower end is rotatably connected to the inside of one side of the metal circular profile via a rotating shaft. The clamping wheel extends above the metal circular profile, and the machine body is fixedly connected to the other side of the metal circular profile.

[0006] Preferably, the lower surfaces of the walking frame and the support frame are provided with track frames, and track wheels are rotatably connected to the lower part of the track frames via a rotating shaft. The support track is wrapped around and covers the outer surfaces of the two track wheels.

[0007] Preferably, the guide wheel is rotatably connected to the walking frame via a mounting bracket, and the height of the guide wheel is higher than that of the supporting track.

[0008] Preferably, the inner end of the support frame is provided with a guide end.

[0009] Compared with the prior art, the beneficial effects of this utility model are: replacing the traditional hot wedge welding equipment with a wheeled bottom structure, while retaining the main structure of the original hot wedge welding equipment, a tracked support structure is designed. Since the flatness of the evaporation pond ground is relatively low and there is an angle at the slope position, the walking mechanism is reduced from getting stuck during operation, thus ensuring the quality of waterproof construction.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4This utility model provides a hot wedge welding device for waterproofing construction of evaporation ponds, including a walking frame 1, a machine body 2 on one side of the walking frame 1, a support frame 3 inside the other side of the walking frame 1, a clamping frame 4 rotatably connected inside the machine body 2 via a rotating shaft, the clamping frame 4 being correspondingly arranged with the support frame 3, support rollers 5 rotatably connected inside both the support frame 3 and the clamping frame 4 via rotating shafts, a welding hot wedge 6 being provided inside the clamping frame 4 and between the upper and lower support rollers 5, a support track 7 being provided on one side of the lower surface of the walking frame 1 and below the support frame 3, a guide wheel 8 being provided on the other side of the lower surface of the walking frame 1, and clamping wheels 9 being provided inside the walking frame 1 and correspondingly on the outer side of the support frame 3 and the clamping frame 4.

[0014] In use, the lower evaporation pond film to be welded passes from the rear of the overall equipment, below the guide wheel 8, then from the upper end of the support frame 3, between the lower support roller 5 and the welding hot wedge 6. The lower support roller 5 supports the lower film, and finally the lower film is output from the upper end of the lower clamping wheel 9. By rotating the support frame 4, the welding hot wedge 6 and the machine body 2 are rotated, increasing the distance between the welding hot wedge 6 and the lower support roller 5 to facilitate film placement. This allows the upper evaporation pond film to be welded to be directly input from the front of the overall equipment onto the upper support roller. Between 5 and the welding hot wedge 6, the final rotating support frame 4 drives the welding hot wedge 6 to rotate, so that the upper and lower support rollers 5 clamp the upper and lower layers of evaporation pond film on the upper and lower surfaces of the welding hot wedge 6. The welding hot wedge 6 heats the lower and upper layers of evaporation pond film simultaneously, and the clamping rollers 9 clamp and bond the heated lower and upper layers of evaporation pond film together. The two layers of evaporation pond film are melted and bonded together by heating, and the entire equipment is pulled to move under the support track 7 set under the walking frame 1 to ensure smooth movement.

[0015] The walking frame 1 is a C-shaped structure consisting of a metal square tube profile and metal circular profiles at both ends. The clamping wheel 9 at the lower end is rotatably connected to the inside of one side of the metal circular profile via a rotating shaft. The clamping wheel 9 extends above the metal circular profile. The body 2 is fixedly connected to the other side of the metal circular profile. Based on the original C-shaped structure of the walking frame 1, a supporting track 7 structure is designed to improve the smoothness of walking.

[0016] The lower surfaces of the walking frame 1 and the support frame 3 are both provided with track frames 10. Track wheels 11 are rotatably connected to the lower part of the track frames 10 via a rotating shaft. The support track 7 is wrapped around and covered on the outer surface of the two track wheels 11. By rotatably connecting the support track 7 to the lower end of the track frame 10 via the track wheels 11, the strength of the support structure is improved while ensuring smooth walking.

[0017] The guide wheel 8 is rotatably connected to the walking frame 1 via the mounting bracket 12. The height of the guide wheel 8 is higher than that of the support track 7, so that the lower evaporation pond film passes through the rear side of the overall equipment, below the guide wheel 8, and then passes through the upper end of the support frame 3 between the lower support roller 5 and the welding hot wedge 6, leaving space.

[0018] The inner end of the support frame 3 is provided with a guide end 13 to guide the lower evaporation pond film.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
