Description

Technical field

[0002] The utility model relates to the technical field of turnover tooling, in particular to the technical field of copper tube fitting turnover in a fin heat exchanger, and in particular to a multifunctional turnover vehicle integrating straight tubes and U-shaped tubes. [Background Technology]

[0004] In the refrigeration and air-conditioning industry, fin heat exchangers are key components for heat exchange, and their performance directly affects the efficiency and operational stability of the entire air-conditioning system. Fin heat exchangers are usually assembled from metal fins and copper tubes through a specific process. The copper tubes serve as a medium for heat conduction, passing between the fins to form an efficient heat exchange channel. Traditionally, the insertion of copper tubes in fin heat exchangers is mostly done manually, meaning workers need to insert the copper tubes one by one into the pre-arranged fin holes and complete the subsequent fixing operations. In order to facilitate the removal of copper tubes and reduce frequent handling, workers usually use turnover vehicles to transport the copper tubes they need to use to a suitable location for removal.

[0005] The copper tubes in the fin heat exchanger are mainly straight copper tubes and U-shaped copper tubes. In the existing manufacturing process, most straight copper tubes are not transported by dedicated turnover vehicles, but by general bucket trucks. The straight copper tubes are stacked too tightly, making it difficult to take them out.

[0006] For the transportation of U-shaped copper tubes, there are special turnover vehicles in the industry. For example, the Chinese invention patent "U-shaped tube turnover vehicle", announcement number: CN103129593B, discloses a U-shaped tube turnover vehicle, including: support legs; crossbeams, arranged at the upper ends of the support legs; and multiple U-shaped tube hanging rods extending outward from the side walls of the crossbeams. The provided U-shaped tube turnover vehicle utilizes support legs, crossbeams arranged at the upper ends of the support legs, and multiple U-shaped tube hanging rods extending outward from the side walls of the crossbeams to achieve an inverted and neat arrangement of U-shaped tubes, solving problems such as the bottom copper tubes being crushed and the copper tubes being entangled.

[0007] Therefore, manufacturers in the refrigeration and air conditioning industry need to equip two types of turnover carts for the copper tubes used in the production of fin heat exchangers: one for straight copper tubes and one for U-shaped copper tubes. This increases production costs and occupies production workshops. Therefore, it is necessary to develop a turnover cart that can transport both straight and U-shaped copper tubes. [Utility Model Content]

[0009] The utility model provides an integrated multifunctional turnover vehicle for straight tubes and U-shaped tubes, which solves the technical difficulties that existing enterprises lack a turnover vehicle specifically for the turnover of straight copper tubes in the production of fin heat exchangers, and also need to be equipped with both straight copper tube turnover vehicles and U-shaped copper tube turnover vehicles.

[0010] The utility model provides a multifunctional turnover vehicle integrating straight tubes and U-shaped tubes, comprising a horizontal support plate, the bottom four corners of the support plate are vertically fixedly connected to support legs, the bottoms of the support legs are spirally connected to universal wheels, and a reinforcement plate is horizontally fixedly connected between two adjacent groups of the support legs, a front guide plate frame is fixed to the top front side of the support plate, a rear guide plate frame is fixed to the top rear side of the support plate, a movement cavity is provided between the front guide plate frame and the rear guide plate, side plates are fixedly connected to the left and right sides of the front guide plate frame and the rear guide frame, the bottoms of the side plates are also fixedly connected to the support plate, an intermediate baffle is vertically slidably connected in the middle between the two groups of side plates, and the intermediate baffle is vertically slidably connected in the middle. The intermediate baffle is located just above the movement cavity, and a hopper bin is formed between the rear guide plate frame, the intermediate baffle and the side plates, and a straight copper tube is placed in the hopper bin. A rotating shaft is rotatably connected in the movement cavity, and both ends of the rotating shaft are rotatably connected to the side plates. A plurality of groove wheels are fixedly connected to the rotating shaft, and the front guide plate frame and the rear guide plate frame are both provided with movement grooves. The groove wheels rotate in the movement grooves, and the straight copper tubes in the hopper bin can be transmitted to the top of the front guide plate frame through the groove wheels. The front guide plate frame, the reinforcement plate and the rear guide plate frame are all provided with a plurality of threaded holes, and hanging rods are spirally connected in the threaded holes, and U-shaped copper tubes are hung on the hanging rods.

[0011] The above technical solution creates a hopper that not only holds straight copper tubes but also allows them to be removed one by one, making them easier for operators to retrieve. Furthermore, when U-shaped copper tubes need to be transported, multiple sets of hanging rods can be screwed in and used to hang the U-shaped copper tubes. This allows one vehicle to serve two purposes.

[0012] Preferably, the top end of the rear guide plate frame is an oblique end face, the rear side of the rear guide plate frame is provided with a rear panel higher than the top oblique end face, and the internal threaded hole provided on the rear guide plate frame is on the rear panel.

[0013] Through the above technical solution, the inclined end surface at the top of the rear guide plate frame facilitates the automatic movement of the straight copper tube to the bottom of the hopper bin. The combination of the rear guide plate frame and the rear panel can improve the capacity of the hopper bin while also helping to control the inclination angle of the inclined end surface at the top of the rear guide plate frame, thereby avoiding the inclined end surface of the rear guide plate frame being made too inclined in order to achieve the gathering function.

[0014] Preferably, a horizontal guide plate is provided on the front side of the top end of the front guide plate frame, an inclined guide plate is provided on the rear side of the top end of the front guide plate frame, the movement groove is on the inclined guide plate, and the internal threaded hole opened on the front guide plate frame is opened on the front side of the front guide plate frame.

[0015] Through the above technical solution, the inclined guide plate at the top of the front guide plate frame can facilitate the separation of the straight copper tube from the groove wheel, and the horizontal guide plate provides effective space for temporarily storing the straight copper tube. Even if the operator fails to take away the copper tube in time, there are still more copper tubes to be temporarily stored, which can give the operator enough reaction time to stop discharging.

[0016] Preferably, the rear end of the hanging rod is provided with a rear external thread, the front end of the hanging rod is provided with a limiting rod, and the hanging rod is spirally connected to the threaded hole through the rear external thread.

[0017] Preferably, the front side of the hanging rod is provided with a front external thread, and the front external thread and the rear external thread are threads with opposite rotation directions but the same tooth profile, nominal diameter, pitch and number of threads. When the hanging rod is not in use, the hanging rod is spirally fixed to the turnover vehicle through the front external thread.

[0018] With the above technical solution, the hanging rod can have only rear external threads or both rear and front external threads. When it has only rear external threads, the hanging rod and the turnover vehicle are separate, and the hanging rod is removed for installation when the U-shaped copper tube needs to be rotated. When the hanging rod has both rear and front external threads, it can be inserted into the threaded hole when it is not needed, and the front external threads can be screwed together to achieve semi-concealed storage of the hanging rod. This prevents the turnover vehicle from occupying unused road space when rotating straight copper tubes.

[0019] Preferably, the side panel is provided with a feed port, the feed port is connected with the hopper bin, a slide groove I is provided in the middle of the side panel, the slide grooves I of the two groups of side panels are relatively arranged for use as a set, the middle baffle slides on the slide groove I, the side panel is also provided with a slide groove II on the edge of the feed port, a side baffle is inserted in the slide groove II, and the switch of the feed port is controlled by plugging and unplugging the side baffle.

[0020] Through the above technical solution, the opening of the side panel feed port can more conveniently stack straight copper tubes into the hopper bin. There is no need to place the copper tubes from the upper opening of the hopper bin, which reduces the handling intensity and is also beneficial to reduce the impact force when the copper tubes are stacked.

[0021] Preferably, the left and right sides of the middle baffle are spirally connected with screw rods, and the screw rods support and are rotatably connected to the side plates.

[0022] According to the above technical solution, the left and right sides of the middle baffle are provided with convex edges extending from the side panels, and the side panels are provided with through slots for the convex edges to move up and down. The side panels are provided with support plates on the upper and lower sides of the through slots, which are rotatably connected to the screw rod, which is helically connected to the convex edge of the middle baffle. The rotation of the screw rod can be controlled manually using a wrench, or by adding a control motor to the screw rod for electric adjustment, but manual adjustment is preferred.

[0023] Preferably, a push handle is fixedly connected to the outer side surface of the side panel on one side.

[0024] Preferably, a motor is connected to one side of the rotating shaft, and the motor is fixed to the side plate.

[0025] Through the above technical solution, when the turnover vehicle arrives at the operation point, the motor is connected to the power supply and the materials can be automatically discharged one by one.

[0026] Preferably, the sheave is provided with a plurality of groups of arc grooves at even angular intervals.

[0027] Through the above technical solution, the arc grooves on the groove wheel can better control the copper tubes to be transported one by one. At the same time, in order to prevent the groove wheel from scratching the copper tubes, the groove wheel is made of rubber.

[0028] Beneficial effects of the utility model:

[0029] 1. The rear guide frame, side panels, and middle baffle form a hopper bin that can hold straight copper tubes. When U-shaped copper tubes need to be transported, multiple sets of hanging rods can be screwed in and hung on them, thus achieving dual uses with one vehicle.

[0030] 2. At the bottom of the middle baffle, there are multiple sets of grooved wheels that rotate in the motion cavity, which can convey the straight copper tubes of the hopper bin one by one, making it convenient for operators to take them.

[0031] 3. The hanging rod has front and rear external threads. The hanging rod can be stored separately from the turnover cart. When the U-shaped copper tube needs to be circulated, the hanging rod can be taken out and installed on the turnover cart. The hanging rod can also be semi-hiddenly screwed on the turnover cart. When it is to be used, the hanging rod can be directly unscrewed and fixed in place for use.

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0049] Example 1

[0050] This embodiment provides a multifunctional turnover vehicle integrating straight tubes and U-shaped tubes, such as Figure 1 As shown, it includes a horizontal support plate 2, the four corners of the bottom of the support plate 2 are vertically fixedly connected with support legs 1, the bottoms of the support legs 1 are spirally connected with universal wheels 12, and a reinforcement plate 10 is horizontally fixedly connected between two groups of adjacent support legs 1.

[0051] like Figure 8-12As shown, a front guide frame 3 is fixed to the front end of the support plate 2, and a rear guide frame 5 is fixed to the rear end of the support plate 2. In this embodiment, a horizontal guide plate 302 is provided at the front end of the front guide frame 3, and an inclined guide plate 301 is provided at the rear end of the front guide frame 3. The front guide frame 3 and the rear guide frame 5 can be formed from bent sheet metal. The rear guide frame 5 has an inclined end surface at the top, and a rear panel 501 is provided at the rear end of the rear guide frame 5, which is higher than the inclined end surface. The rear panel 501 is fixed to the rear guide frame 5 by welding or screws.

[0052] A movement cavity 17 is formed between the front guide plate frame 3 and the rear guide plate frame 5 without contact. The left and right sides of the front guide plate frame 3 and the rear guide plate frame 5 are fixedly connected with side plates 4 by bolts, and the bottom of the side plates 4 is also fixedly connected with the support plate 2 by bolts.

[0053] like Figure 1-2 As shown, an intermediate baffle 6 is vertically slidably connected in the middle between the two sets of side panels 4. The intermediate baffle 6 is located directly above the motion chamber 17. In this embodiment, a chute I 402 is provided in the middle of the side panels 4. The chute I 402 of the two sets of side panels 4 are arranged relative to each other as a set, and the intermediate baffle 6 slides within the chute I 402. A hopper is formed between the rear guide frame 5, the intermediate baffle 6, and the side panels 4. A straight copper tube 8 is placed in the hopper.

[0054] like Figure 8-12 As shown, a rotating shaft 18 is rotatably connected within the motion chamber 17. Both ends of the rotating shaft 18 are rotatably connected to the side panels 4. Multiple sets of sheaves 16 are fixedly connected to the rotating shaft 18. In this embodiment, one end of the rotating shaft 18 is connected to a motor (not shown). This motor is a conventional low-speed motor fixed to the side wall of the side panel 4. When the turnover vehicle is moved to its operating position, the motor is simply connected to a power outlet.

[0055] In this embodiment, the groove wheel 16 is evenly provided with multiple groups of arc grooves 1601 at equal angles. The arc grooves 1601 on the groove wheel 16 can better control the copper tubes to be transmitted one by one. At the same time, in order to prevent the groove wheel 16 from scratching the copper tubes, the material of the groove wheel 16 is rubber.

[0056] like Figure 4 and Figure 7 As shown, both the front guide plate frame 3 and the rear guide plate frame 5 are provided with a motion groove 15 , in which a groove wheel 16 rotates. The straight copper tube 8 in the hopper bin can be transferred to the top of the front guide plate frame 3 through the groove wheel 16 .

[0057] In this embodiment, Figure 1 、 5 As shown in Figures 6 and 7, the front side of the front guide plate frame 3 is provided with multiple sets of threaded holes 19, the rear panel 501 is also provided with multiple sets of threaded holes 19, and the front and rear reinforcement plates 10 are also provided with multiple sets of threaded holes 19. The threaded holes 19 are spirally connected to the hanging rods 9, and the U-shaped copper tubes 11 are hung through the hanging rods 9.

[0058] In this embodiment, Figure 1 and 6 As shown in , one of the threaded holes 19 opened on the front side of the front guide plate frame 3 is on a horizontal line, and the threaded holes 19 opened on the front and rear reinforcement plates 10 are also on a horizontal line, while the threaded holes 19 opened on the rear panel 501 are on multiple parallel horizontal lines. At the same time, the groups of threaded holes 19 opened on the front guide plate frame 3 and the front reinforcement plate 10 correspond one by one on a vertical plane, and the groups of threaded holes 19 opened on the rear panel 501 and the rear reinforcement plate 10 also correspond one by one on a vertical plane. When in use, the upper hanging rod 9 hangs the U-shaped copper tube 11, and the lower hanging rod 9 is used to prevent the U-shaped copper tube 11 from shaking significantly. At the same time, because the rear panel 501 is higher, multiple groups of threaded holes 19 of different horizontal heights are provided, so on the side of the rear panel 501, a hanging rod 9 of a suitable height can be selected to hang the U-shaped copper tube 11 according to the length of the U-shaped copper tube 11. As shown in Figure 1 and 6 As shown, a pair of hanging rods 9 are drawn at the front and back, each of which has U-shaped copper tubes 11 of two specifications hung thereon. In actual use, this paired usage mode is referred to.

[0059] In this embodiment, Figure 5 As shown, the rear end of the hanging rod 9 is provided with a rear external thread 901, and the front side of the hanging rod 9 is provided with a front external thread 902. The front external thread 902 and the rear external thread 901 are threads with opposite rotation directions but the same thread profile, nominal diameter, pitch, and number of threads. The front end of the hanging rod 9 is provided with a limit rod 903. The hanging rod 9 is screwed into the threaded hole 19 via the front external thread 902 or the rear external thread 901. When the hanging rod 9 is not in use, the hanging rod 9 is screwed to the turnover vehicle via the front external thread 902; when the hanging rod 9 is in use, it is screwed into the threaded hole 19 via the rear external thread 901.

[0060] The hanging rod 9 may have only the rear external thread 901, or may have both the rear external thread 901 and the front external thread 902. When it has only the rear external thread 901, the hanging rod 9 and the turnover vehicle are separate, and when the U-shaped copper tube 11 needs to be rotated, the hanging rod 9 is removed for installation. When the hanging rod 9 has both the rear external thread 901 and the front external thread 902, when the hanging rod 9 is not needed, the hanging rod 9 can be inserted into the threaded hole 19, and the front external thread 902 is spirally connected to the threaded hole 19 to achieve semi-hidden storage of the hanging rod 9. This prevents the turnover vehicle from occupying invalid road space when rotating the straight copper tube 8.

[0061] In this embodiment, Figure 1-3As shown, the side panel 4 is provided with a feed port 401, which is connected to the hopper bin. The side panel 4 is also provided with a chute II 403 next to the feed port 401, and a side baffle 7 is inserted into the chute II 403. The opening and closing of the feed port 401 is controlled by plugging and unplugging the side baffle 7.

[0062] The opening of the feed port 401 on the side panel 4 makes it easier to stack the straight copper tubes 8 into the hopper bin. There is no need to place the copper tubes from the upper opening of the hopper bin, which reduces the handling intensity and is also beneficial to reducing the impact force when the copper tubes are stacked.

[0063] In this embodiment, Figure 1 and 3 As shown, the left and right sides of the middle baffle 6 are spirally connected with screw rods 14, which support and rotate to connect to the side plates 4. Figure 3 As shown, the left and right sides of the middle baffle 6 are provided with convex edges extending from the side panels 4. The side panels 4 are provided with through slots for the convex edges to move up and down. The side panels 4 are provided with support plates on the upper and lower sides of the through slots. The support plates are connected by rotating screws 14, which are helically connected to the convex edges of the middle baffle 6. By rotating the left and right screws 14 simultaneously, the middle baffle 6 can be controlled to slide up and down in the slide slot I 402.

[0064] In this embodiment, Figure 1 As shown, the outer side of one side side plate 4 is fixedly connected with a push handle 13. The push handle 13 is used to push and control the turnover vehicle to travel.

[0065] Turnover straight copper tube 8 hours:

[0066] The hanging rod 9 is screwed into each threaded hole 19 through the front external thread 902, and the hanging rod 9 is stored in a semi-hidden manner. Then the turnover vehicle in this embodiment is pushed to the copper tube production area by the push handle 13 for loading. Pull the side baffle 7 upwards, pull one of the side baffles 7 out of the chute II 403, and open the feed port 401 on this side. Then the straight copper tubes 8 are stacked into the hopper bin from the side feed port 401. After the hopper bin is full of straight copper tubes 8, the side baffle 7 that was originally pulled out is reinserted into the chute II 403, and then the turnover vehicle is pushed to the pipe insertion operation area. The personnel in the operation area plug the power cord of the motor into the socket, power on the motor, and control the motor movement. The motor drives the rotating shaft 18 to rotate, which in turn drives the sheave 16 to rotate. After the sheave 16, through friction, moves a copper tube into a set of arcuate grooves 1601, the straight copper tube 8 rotates with the sheave 16 and is transmitted from the hopper bin to the top of the front guide plate frame 3. The inclined guide plate 301 on the rear side of the front guide plate frame 3 first contacts the straight copper tube 8. Under the support of the inclined guide plate 301, the straight copper tube 8 disengages from the sheave 16 and, under its own weight, rolls down onto the horizontal guide plate 302. This enables the tubes to be discharged one by one. The discharge rate is controlled by controlling the motor speed. For smooth discharge, it is best not to pile the straight copper tubes 8 in the hopper bin too cluttered or too full.

[0067] Turnover U-shaped copper tube 11:

[0068] The hanging rod 9, which is semi-hidden and fixed in the threaded hole 19, is unscrewed a little to disengage the front external thread 902 of the hanging rod 9 from the threaded hole 19. Then, when the rear external thread 901 of the hanging rod 9 contacts the threaded hole 19 during the process of moving the hanging rod 9 outward, the hanging rod 9 is rotated again to screw the rear external thread 901 of the hanging rod 9 into the threaded hole 19, thereby extending the hanging rod 9 and screwing it onto the turnover vehicle. Only the bottom of the rear panel 501 can semi-hide the hanging rod 9. If the rotating U-shaped copper tube 11 is too long and it is not appropriate to use the hanging rod 9 on the side of the front guide plate frame 3 to hang the U-shaped copper tube 11, the threaded hole 19 at an appropriate height on the rear panel 501 can be used according to the actual length of the U-shaped copper tube 11. In this case, the U-shaped copper tube 11 will not be hung on the side of the front guide plate frame 3. After the turnover vehicle is fully hung with U-shaped copper tubes 11, the turnover vehicle can be pushed to the copper tube insertion operation area for use.

[0069] The above embodiments are only examples of implementation methods of the present invention. For those skilled in the art, it is easy to make various types of improvements or modifications based on the application methods and principles disclosed in the present invention, and are not limited to the structures or methods described in the above specific implementation methods of the present invention. Therefore, the method described above is only a preferred option and does not have a restrictive meaning. All equivalent changes and modifications made according to the present invention are within the scope of protection of the claims of the present invention.
