[0002] Exhaust gas from spray painting workshops contains various impurities and cannot be discharged directly. Connecting a filter box to the exhaust duct can filter specific impurities from the exhaust gas. With existing technology, the larger the filter box, the longer its effective filtration time, so the filter box is getting larger and larger.

[0003] Currently, replacing large filter boxes in exhaust ducts is difficult, primarily due to the difficulty in moving the filter boxes and aligning the inlet and outlet ports with the exhaust duct. This operation requires heavy lifting equipment and multiple workers, making filter element replacement cumbersome, inefficient, and costly. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning trolley for replacing filter elements to solve the above-mentioned problems existing in the prior art.

[0017] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0018] like Figure 1 and Figure 2 As shown, a positioning trolley for replacing a filter element comprises a carrying chassis 1 and a filter box 2 mounted on the carrying chassis 1. The carrying chassis 1 is slidably arranged on a track 6. A buffer return member 13 and a non-return tail top 14 are respectively provided at both ends of the carrying chassis 1. The buffer return member 13 and the non-return tail top 14 cooperate with a structure 7 to position the carrying chassis 1.

[0019] The utility model sets the filter box 2 on the carrying chassis 1, and reduces the difficulty of transporting the filter box 2 through the cooperation of the sliding wheel set 12 and the track 6, avoids the introduction of lifting equipment, and reduces the difficulty and cost of transporting the filter box 2; in addition, the utility model realizes the precise positioning of the carrying chassis 1 through the cooperation of the buffer return top piece 13 and the non-return tail top 14 with the structure 7, so that the air port 1 22 and the air port 2 23 of the filter box 2 can be quickly aligned with the exhaust pipe, avoiding the tedious process of replacing the filter element of the filter box 2 and improving the efficiency of filter element replacement.

[0020] like Figure 1 and Figure 3 As shown, the transport chassis 1 includes a frame 11 and two sets of sliding wheel groups 12 arranged on the frame 11. The sliding wheel groups 12 are slidably connected to the track 6. The buffer return member 13 and the anti-return tail top 14 are respectively arranged at both ends of the frame 11.

[0021] Specifically, the sliding wheel group 12 includes a rotating shaft, wheels connected to both ends of the rotating shaft and a shock-absorbing member for connecting the rotating shaft to the frame 11. In order to prevent the wheels from leaving the track 6 during the operation of the transport chassis 1, the inner side of the wheel tread is selected to be an edge structure.

[0022] Among them, the anti-return tail top 14 includes a connecting rod 141 and an anti-wear roller 142. One end of the connecting rod 141 is hinged on the rotating shaft of a set of sliding wheel groups 12, and the anti-wear roller 142 is hinged on the other end of the connecting rod 141. The anti-wear roller 142 cooperates with the tail top step 71 of the structure 7. When the anti-wear roller 142 falls into the tail top step 71, the anti-return tail top 14 limits the reverse operation of the carrying chassis 1.

[0023] Two groups of check tail tops 14 can be provided on the rotating shaft, and the two groups of check tail tops 14 operate independently to prevent positioning failure caused by failure of a single group of check tail tops 14. The axial positioning of the connecting rod 141 on the rotating shaft is achieved by a retaining spring.

[0024] The introduction of the anti-wear roller 142 is to reduce the wear of the structure 7 on the check tail 14 on the one hand, and to prevent the check tail 14 from being squeezed too hard in the tail step 71 and being difficult to remove on the other hand.

[0025] Specifically, the anti-return tail pin 14 also includes a reset rod 143 mounted on the connecting rod 141. With the help of the anti-wear roller 142, pulling the reset rod 143 lifts the connecting rod 141, breaking the reverse lock between the anti-return tail pin 14 and the tail pin step 71. The length of the connecting rod 141 is required to ensure that when the anti-wear roller 142 contacts the structure 7, the angle between the connecting rod 141 and the track 6 is acute, with an angle of 30 to 45 degrees being optimal. This is to reduce the force required to remove the anti-return tail pin 14.

[0026] The buffer return member 13 includes a spring and an impact plate. The impact plate is installed at one end of the spring, and the other end of the spring is connected to the frame 11. The buffer return member 13 cooperates with the structure 7. When the impact plate contacts the structure 7, the spring absorbs the buffer, and the buffer return member 13 limits the forward movement of the carrying chassis 1.

[0027] like Figure 1 and Figure 4 As shown, the filter box 2 and the housing 21 include the housing 21 and the filter material 24 filled therein. The housing 21 is provided with an air port 1 22 and an air port 2 23, which are respectively connected to the lower ventilation pipe 4 and the upper ventilation pipe 3. The upper ventilation pipe 3 and the air port 2 23, as well as the lower ventilation pipe 4 and the air port 1 22, are both sealed by connectors 5. The locations of the air ports 1 22 and 23 on the housing 21 are related to the layout of the external pipes and are not specifically limited here. In this embodiment, vertical positions are used to reduce the adhesion of paint particles in the air to the pipe walls.

[0028] During use, the filter box 2 is mounted on the vehicle frame 11 at a designated location, and the carrier chassis 1 is then pushed along the track. During sliding, the buffer return member 13 first contacts the structure 7. As the spring compresses and contracts, the anti-wear roller 142 precisely reaches the tail top step 71. Under the action of gravity, the anti-wear roller 142 falls onto the tail top step 71. As the spring recovers its deformation, the buffer return member 13 returns to the vehicle frame 11. The dual action of the buffer return member 13 and the anti-return tail stop 14 secures the carrier chassis 1, thereby securing the filter box 2 in place.

[0029] Then connect to filter box 2 and exhaust pipe and get final product.When needs change filter element, pull reset pull rod 143, the non-return tail top 14 is taken out from tail top step 71 and can recover carrying chassis 1 on track 6 and lead to move.

[0030] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
