Description

Technical Field

[0001] This utility model belongs to the technical field of air cooler component manufacturing equipment, and particularly relates to an end plate assembly and positioning device. Background Technology

[0002] End plates come in two types: threaded plug plates and tube plates. They are plate-shaped structural components used to support both ends of the finned tube. The tube plate has multiple through holes for inserting the ends of the finned tubes, while the threaded plug plate has multiple threaded holes for inserting the other end of the finned tube. Before installing the finned tubes, the tube plate and threaded plug plate need to be installed separately. Figure 1 The two symmetrically arranged side plates shown require that the height of the tube plates and the plug plates at both ends be kept consistent during installation to ensure that the holes on the tube plates correspond one-to-one with the holes on the plug plates, thus ensuring the horizontality of the finned tube installation.

[0003] The existing tube sheet or threaded plug plate installation methods all adopt the hoisting method. A hoisting rope is set at the output end of the crane, and the two ends of the tube sheet or threaded plug plate are respectively threaded on the hoisting rope. Then, the tube sheet or threaded plug plate is hoisted to the corresponding end of the side plate by the crane, thereby connecting the two ends of the tube sheet or threaded plug plate with the side plates on both sides, and the connection is welded and fixed by a welding gun.

[0004] However, the lifting rope undergoes plastic deformation downwards due to the weight of the tube sheet or plug plate. The amount of deformation cannot be guaranteed to be consistent, and the two ends of the tube sheet or plug plate may be tilted to the horizontal plane, thus affecting the installation of finned tubes. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an end plate assembly positioning device that ensures that the two ends of the end plate remain horizontal when assembled on the two ends of the side plate, avoiding tilting and improving assembly accuracy.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed:

[0007] An endplate assembly positioning device, comprising:

[0008] The support assembly includes an L-shaped base frame, with a set of casters on the bottom surface of the horizontal section of the base frame;

[0009] The lifting assembly includes a hydraulic cylinder vertically mounted on the bottom surface of the horizontal part of the base frame. The hydraulic cylinder is located between a set of casters. The output end of the hydraulic cylinder passes vertically upward through the bottom surface of the base frame and is provided with a bearing plate. Vertical plates are provided at both ends of the bearing plate. The vertical plates are vertically slidably connected to the vertical part of the base frame. A set of vertically spaced screws are provided on one side of the vertical plate. Locking nuts are fitted on the screws to fix the end plates.

[0010] Furthermore, the vertical part of the base frame has an inverted E-shaped structure, with a vertical groove on one side of the horizontal part at both ends and a C-shaped push handle on the other side.

[0011] Furthermore, the cross-section of the chute is T-shaped, and the cross-section of the vertical plate is I-shaped. One end of the horizontal part of the I-shaped vertical plate is adapted to the horizontal part of the T-shaped chute, and the other end of the horizontal part extends out of the vertical part of the chute and is connected to the screw.

[0012] Furthermore, a rectangular groove is recessed on the side of the vertical plate facing the slide groove, and a row of rollers is arranged vertically along the rectangular groove, with the rollers slidably connected to the slide groove.

[0013] Furthermore, the bottom surface of the horizontal section of the base frame is provided with mounting bases, and the casters are respectively mounted on the corresponding mounting bases.

[0014] The beneficial effects of this utility model are as follows:

[0015] The lower side of the end plate along its length is supported by a support plate, allowing the end plate to be placed vertically on the support plate. A screw passes through the corresponding hole on the end plate, and a lock nut is used to lock the end plate to the vertical plate. The side with the screw is pressed against the side of the end plate, thus ensuring the verticality and horizontality of the end plate during assembly, thereby improving the accuracy of the end plate assembly.

Detailed Implementation

[0025] To make the objectives, technical solutions and advantages of the embodiments of this utility model clearer, the implementation methods of this utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this utility model are only some embodiments of this utility model, and not all embodiments.

[0026] like Figures 2-7 As shown, this example provides an end plate assembly positioning device for positioning the tube plate 1 or the plug plate 2 when installing the tube plate 1 and the plug plate 2 at both ends of the side plate 3. The device includes a support assembly 10 and a lifting assembly 20.

[0027] Specifically, such as Figures 4-5 As shown, the support assembly 10 includes an L-shaped base frame 11. The vertical part of the base frame 11 has an inverted E-shaped structure. A vertical groove 111 is provided on one side of the horizontal part at both ends. The cross-section of the groove 111 is T-shaped. A C-shaped push handle 112 is connected to the other side of the vertical part of the base frame 11. A set of symmetrically arranged connecting seats 113 are provided at intervals on the bottom surface of the horizontal part of the base frame 11. A universal wheel 12 is installed on the bottom surface of each connecting seat 113.

[0028] like Figures 3-4 , Figure 6 As shown, the lifting assembly 20 includes a hydraulic cylinder 21, a support plate 22, and a vertical plate 23. The hydraulic cylinder 21 is located on the bottom surface of the horizontal part of the L-shaped base frame 11 and is vertically arranged, with its output end vertically upward through the horizontal part of the L-shaped base frame 11. The support plate 22 is arranged parallel to the horizontal part of the L-shaped base frame 11 above it, and the width of the support plate 22 is greater than the thickness of the end plate. The vertical plate 23 has an I-shaped cross-section and is symmetrically arranged on the side of the support plate 22 facing the vertical part of the L-shaped base frame 11, and the vertical plate 23 is perpendicular to the support plate 22.

[0029] A set of screws 231 are vertically spaced on the horizontal part of the vertical plate 23 away from the vertical part of the base frame 11. Each screw 231 is threaded with a locking nut 232. A rectangular groove 233 is recessed on the horizontal part of the vertical plate 23 facing the vertical part of the base frame 11. A row of rollers 234 are vertically arranged in the rectangular groove 233.

[0030] During installation, place the bearing plate 22 horizontally on the top surface of the horizontal part of the L-shaped base frame 11, and align the horizontal part of the vertical plate 23 with the roller 234 with the horizontal part of the slide groove 111, allowing the roller 234 to slide against the horizontal edge of the slide groove 111. Install the screw 231 on the other horizontal part of the vertical plate 23, with the length of the screw 231 being greater than the thickness of the end plate. Then, thread the locking nut 232 onto the corresponding screw 231.

[0031] Specific usage process:

[0032] Lower the support plate 22 to the bottom surface of the horizontal part of the base frame 11, transfer the two ends of the end plate to the support plate 22 in a vertical state, and place the lower side of the end plate on the support plate 22. Then move the end plate towards the vertical plate 23 so that the hole on the end plate passes through the corresponding screw 231 until the end plate is close to the side of the vertical plate 23 where the screw 231 is installed, and then stop moving the end plate to ensure the parallelism of the two ends of the end plate in the horizontal direction.

[0033] Then, the locking nuts 232 are screwed into the corresponding screws 231 in sequence. The verticality of the end plate is ensured by the bearing plate 22 cooperating with the side of the vertical plate 23 on which the screws 231 are installed.

[0034] Finally, push the pusher 112 to transfer the end plate to one end of the side plate 3, so that both ends of the end plate are spliced ​​with the ends of the side plates 3 on both sides, as follows. Figure 7 As shown, hydraulic cylinder 21 is activated, causing it to push the bearing plate 22 upwards, thus moving the end plate vertically upwards. Simultaneously, under the upward pushing action of hydraulic cylinder 21, it bears the force on the base frame 11. When the centerline of the long axis of the end plate and the centerline of the long axis of the side plate 3 are on the same horizontal plane, hydraulic cylinder 21 is paused, and a welding torch is used to weld and fix the joint between the end plate and the side plate 3. This ensures that when the end plate is assembled with the two ends of the side plate 3, both ends of the end plate remain on the same horizontal plane, improving assembly accuracy.

[0035] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
