[0039] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0040] like Figures 1 to 5 As shown, this embodiment provides a wedge assembly device, including:

[0041] The parking cylinder press-fitting device 1 comprises a support frame 11, a positioning plate 12, a cylindrical pressure head 13 that can move up and down, a driving device 14 and an alignment column 15; the pressure head 13 and the positioning plate 12 are arranged on the support frame 11 with an upper and lower interval, and the positioning plate 12 is used to place and align the parking cylinder body 31 of the parking cylinder 3; the alignment column 15 can be inserted into the center hole of the parking cylinder cover 32 and the inner hole of the parking piston after placing the parking piston and the parking spring in the parking cylinder body 31 and covering the parking cylinder cover 32 of the parking cylinder 3; the pressure head 13, the alignment column 15 and the positioning plate 12 are coaxially arranged, the driving device 14 is connected to the pressure head 13, and can drive the pressure head 13 to move downward to press the upper end surface of the parking cylinder cover 32;

[0042] And a wedge-shaped body mounting device 2, which includes a mounting frame 21, a first limiting plate 22, a power column 23 and a second limiting plate 24; the first limiting plate 22 is installed on the mounting frame 21, and the first limiting plate 22 is parallel to the bottom surface of the mounting frame 21 and forms a accommodating limiting space for placing the parking cylinder 3 between the first limiting plate 22 and the bottom surface of the mounting frame 21; a limiting groove 221 is provided on the first limiting plate 22, which is used to accommodate a parking screw sleeve 33 that is limitedly penetrated in the parking cylinder 3; the power column 23 can be placed between the U-shaped body of the wedge-shaped body 4 of the brake cylinder, and is circumferentially fixed to the wedge-shaped body 4 through the second limiting plate 24; a torque wrench insertion hole 231 (for example, a square hole) is provided on the power column 23.

[0043] Among them, the parking cylinder press-fitting device 1 is used to press-fit the parking spring of the parking cylinder 3 into the parking cylinder cylinder cover 32, and the wedge-shaped body installation device 2 is used to install the wedge-shaped body assembly on the parking cylinder 3. The brake cylinder mentioned in this article is an air brake. When in use, the parking cylinder body 31 is placed on the positioning plate 12, the parking piston is placed in the parking cylinder body 31, and the parking spring is put on the parking piston. After the parking cylinder cylinder cover 32 is covered, the alignment column 15 is used to insert the parking cylinder cylinder cover 32 and the parking piston for alignment, and then the driving device 14 is used to drive the pressure head 13 to move downward, and the parking cylinder cylinder cover 32 and the parking cylinder body 31 are pressed tightly. After pressing, the corresponding bolts are inserted to achieve the fastening of the parking cylinder body 31 and the parking cylinder cover 32. After that, first insert the parking screw sleeve 33 into the installed parking cylinder 3, then push the parking cylinder 3 into the accommodating limit space, place the wedge body 4 on the first limit plate 22, and then insert the torque wrench into the torque wrench insertion hole 231. By applying the torque wrench, the wedge body 4 is driven to rotate, and the wedge body assembly can be quickly installed into the parking cylinder 3.

[0044] Therefore, the wedge assembly device of this embodiment is suitable for existing brake caliper unit products of railway locomotives and vehicles, and can be used to first press-fit the parking spring of the parking cylinder 3 into the parking cylinder cover 32, and then assemble the wedge assembly onto the parking cylinder 3. When the parking spring is placed into the parking cylinder body 31 and the parking cylinder cover 32 is press-fitted by the parking cylinder press-fitting device 1, alignment can be ensured, and the press-fitting efficiency is high; when the wedge assembly is installed on the parking cylinder 3 by the wedge installation device 2, the cooperation of the mounting frame 21, the first limit plate 22, the power column 23 and the second limit plate 24 can facilitate the rapid installation of the wedge assembly, and the installation efficiency is higher, saving time and labor. Through the cooperation of the parking cylinder press-fitting device 1 and the wedge installation device 2, the press-fitting of the parking spring in the parking cylinder 3 and the assembly of the wedge assembly on the parking cylinder 3 are realized, and the operation is more convenient, the labor intensity is low, and the work efficiency is higher.

[0045] In a specific implementation, in order to facilitate the centering of the parking cylinder body 31 by the positioning plate 12, refer to Figure 1 The positioning plate 12 is provided with a plurality of second positioning posts 121 , and the plurality of second positioning posts 121 can be inserted into a plurality of mounting holes on the parking cylinder body 31 .

[0046] In one embodiment, in order to better ensure the alignment of the parking cylinder head 32 and the parking cylinder body 31 during the press-fitting process, refer to Figure 2 and Figure 3The positioning plate 12 can rotate around its own axis. The parking cylinder press-fitting device 1 also includes a plurality of temporary positioning rods 16. The temporary positioning rods 16 can be inserted into corresponding mounting holes on the upper and lower sides of the parking cylinder body 31 and the parking cylinder cover 32 after the parking piston and the parking spring are placed in the parking cylinder body 31 and the parking cylinder cover 32 is covered.

[0047] Among them, the currently commonly used parking cylinders 3 include a first type parking cylinder 34 and a second type parking cylinder, which are two different types of parking cylinders 3, both of which are existing structures and have the same function, both of which are used for parking brakes; these two types of parking cylinders 3 both include a parking cylinder body 31 and a parking cylinder head 32, and a parking piston and a parking spring are arranged in the parking cylinder body 31. When actually assembling the brake cylinder, only one parking cylinder 3 needs to be assembled, and a matching parking cylinder 3 is selected according to the type of the brake cylinder.

[0048] The parking cylinder body 31 and the parking cylinder cover 32 both have a center hole (through hole) and a mounting hole. Figure 2 As shown, it is generally square and has eight groups of mounting holes, each group of mounting holes includes a mounting hole that axially penetrates the parking cylinder body 31 and a mounting hole that axially penetrates the parking cylinder head 32; four groups of mounting holes are used to pass four bolts to fix the parking cylinder body 31 and the parking cylinder head 32, and the other four groups of mounting holes are used to pass four bolts to fix the parking cylinder 3 and the intermediate body. Therefore, when the parking cylinder press-fitting device 1 is used to press-fit the cylinder head, four temporary positioning rods 16 are first passed through the four groups of mounting holes used to connect the intermediate body, and after the cylinder head is pressed onto the cylinder body, the temporary positioning rods 16 are removed after the bolts are installed in the four groups of mounting holes used to connect the cylinder body and the cylinder head.

[0049] For the second type of parking cylinder, it is generally cylindrical and has four groups of mounting holes for inserting four bolts to fix the parking cylinder 3 to the intermediate body. Each group of mounting holes includes a mounting hole (blind hole) that does not penetrate the parking cylinder body 31 in the axial direction and a mounting hole (through hole) that penetrates the parking cylinder cover 32 in the axial direction. The cylinder body and the cylinder cover are clamped and fixed by corresponding clamping rings. Therefore, when the cylinder cover is pressed by the parking cylinder press-fitting device 1, it is not necessary to insert the above-mentioned temporary positioning rod 16. The cylinder cover can be clamped and fixed with the cylinder body by just pressing it.

[0050] Furthermore, the pressure head 13 is a cylindrical structure with an opening at the bottom, and a plurality of through holes (such as oblong holes) can be provided on its side wall to facilitate observation of the internal conditions and to reduce weight. When the pressure head 13 moves downward to press the parking cylinder cover 32, the alignment column 15 is accommodated in the pressure head 13.

[0051] The alignment column 15 is mainly used to ensure the alignment of the parking cylinder body 31 and the parking cylinder cover 32. Its structure can be determined according to needs. For example, in this embodiment, refer to Figure 2 and Figure 3 The alignment column 15 includes a handle 151, a main column 152 and a guide column 153 connected in sequence from top to bottom. At least the bottom diameter of the main column 152 matches the central hole diameter of the parking cylinder cover 32. The diameters of the guide column 153 and the handle 151 are both smaller than the diameter of the main column 152, and the diameter of the guide column 153 matches the inner hole diameter of the parking piston. The guide column 153 mainly plays a guiding role. The upper part of the main column 152 can be arranged according to the following steps: Figure 3 Shown in FIG. 1 is a conical surface whose diameter tapers upward.

[0052] The positioning plate 12 is made rotatable, mainly for the convenience of rotating the parking cylinder 3 when installing the temporary positioning rod 16. Generally, the positioning plate 12 is connected to the support frame 11 through a bearing, and the positioning plate 12 is manually rotated.

[0053] The driving device 14 can be, for example, a cylinder, the piston rod of which is vertically arranged and the bottom end of which is fixedly connected to the pressure head 13, so as to drive the pressure head 13 to move up and down. A switch is also provided on the support frame 11, and the switch is used to control the action of the cylinder. The switch can be, for example, a hand valve, and the operator can manually operate the hand valve to control the cylinder to move up or down.

[0054] The parking cylinder press-fitting device 1 is used to press-fit the parking spring into the parking cylinder cover 32. Taking the press-fitting of the first type parking cylinder 34 as an example, the press-fitting process is specifically as follows:

[0055] The parking cylinder body 31 is placed on the positioning plate 12, so that the multiple positioning columns 121 on the positioning plate 12 are respectively inserted into the multiple mounting holes of the parking cylinder body 31, so as to realize the centering positioning of the parking cylinder body 31. Then the parking piston is placed in the parking cylinder body 31, the parking spring is placed on the parking piston, and the parking cylinder cover 32 is covered; the alignment column 15 is inserted into the center hole of the parking cylinder cover 32 and the inner hole of the parking piston, so as to realize the vertical alignment of the parking cylinder body 31 and the parking cylinder cover 32.

[0056] Next, a plurality of temporary positioning rods 16 are inserted into the corresponding mounting holes of the parking cylinder body 31 and the parking cylinder cover 32. After installing one temporary positioning rod 16, the positioning plate 12 is manually rotated, and then the next temporary positioning rod 16 is installed, so that the vertical alignment of the parking cylinder body 31 and the parking cylinder cover 32 is effectively guaranteed. The driving device 14 is used to drive the pressure head 13 downward to press down the upper end surface of the parking cylinder cover 32 to press the parking cylinder cover 32 and the parking cylinder body 31 tightly. After pressing, bolts are inserted into the corresponding mounting holes. After the four bolts are installed (the bolts are manually pre-installed and then torqued using an electric torque wrench), the parking cylinder body 31 and the parking cylinder cover 32 can be fastened together, and then each temporary positioning rod 16 can be removed to complete the pressing of the parking spring into the parking cylinder cover 32.

[0057] Further, in order to facilitate the mounting frame 21 to limit the parking cylinder 3, refer to Figure 4 The mounting frame 21 includes a bottom plate 211, an end plate 212 and two side plates 213 arranged on the top surface of the bottom plate 211, the first limiting plate 22 is connected to the end plate 212, and the first limiting plate 22, the end plate 212, the bottom plate 211 and the two side plates 213 enclose a accommodating limiting space.

[0058] In order to facilitate the second limiting plate 24 to circumferentially fix the wedge-shaped body 4, the power column 23 passes through the center of the second limiting plate 24 and is connected (fixed) to the second limiting plate 24. Slots 241 are provided at both ends of the second limiting plate 24. The two slots 241 of the second limiting plate 24 can be respectively inserted into the two pull rods 41 of the U-shaped body.

[0059] Among them, the structure of the wedge 4 is the prior art, refer to Figure 5 The wedge-shaped body 4 includes a U-shaped body, which is composed of two tie rods 41 and a connecting rod. The sides of the two tie rods 41 have wedge-shaped surfaces. A screw is connected to the bottom of the U-shaped body, and the wedge-shaped body 4 and the screw constitute a wedge-shaped body. When the brake cylinder is working, the wedge-shaped surface of the wedge-shaped body 4 cooperates with the common cylinder to transmit the parking force. The parking screw sleeve 33 is a tubular structure with openings at both ends, the upper part of which is a cylindrical structure and the inner wall has an internal thread, and the lower outer wall is a conical surface, and the diameter of the conical surface gradually increases from top to bottom; after the parking screw sleeve 33 is inserted into the parking cylinder 3, the screw is inserted into the parking screw sleeve 33 and threadedly connected thereto, so that the connection between the two can be achieved.

[0060] The two side plates 213 of the mounting frame 21 are parallel to each other and perpendicular to the end plate 212. The bottom plate 211, the end plate 212, the two side plates 213, the first limiting plate 22, and the second limiting plate 24 of the mounting frame 21 can all be rectangular plates. The distance between the two side plates 213 matches the width of the parking cylinder 3. The distance between the first limiting plate 22 and the bottom plate 211 should be greater than the height of the parking cylinder 3. After the parking cylinder 3 is pushed to the accommodation limiting space, the parking cylinder 3 rests on the end plate 212. There is a small gap between the two side plates 213 and the two sides of the parking cylinder 3 to limit the parking cylinder 3.

[0061] One end of the first limiting plate 22 is vertically fixed to the end plate 212, and the other end thereof is provided with a limiting slot 221 to accommodate and limit the parking screw sleeve 33. The axis of the power column 23 is perpendicular to the plate surface of the second limiting plate 24, and the two form a cross structure; the second limiting plate 24 is provided with slots 241 at both ends to form an H-shape as a whole, which can also be regarded as an I-shape.

[0062] In this embodiment, the wedge-shaped body installation device 2 is used to install the wedge-shaped body assembly on the parking cylinder 3. The installation process is specifically as follows:

[0063] The parking screw sleeve 33 is inserted from bottom to top into the parking cylinder 3 installed by the parking cylinder press-fitting device 1, specifically, the parking screw sleeve 33 passes through the center hole of the parking cylinder body 31 and the center hole of the parking cylinder cover 32 from bottom to top in sequence, and passes through the parking cylinder cover 32 upward; since the lower part of the parking screw sleeve 33 is a conical surface, the lower outer diameter of the conical surface is larger than the aperture of the parking cylinder body 31, after the parking screw sleeve 33 is inserted into the parking cylinder 3, the parking screw sleeve 33 is fixedly connected to the parking cylinder 3. Then, the parking cylinder 3 with the parking screw sleeve 33 installed is pushed into the accommodating limiting space according to the orientation of the cylinder body at the bottom and the cylinder cover at the top, so as to limit the parking cylinder 3, and at this time, the parking screw sleeve 33 is inserted into the limiting groove 221 of the first limiting plate 22.

[0064] The wedge 4 is placed on the first limit plate 22, and the screw is inserted into the parking screw sleeve 33. The power column 23 is placed between the two pull rods 41 of the wedge 4, and the two slots 241 at both ends of the second limit plate 24 are inserted into the two pull rods 41 of the wedge 4 to achieve circumferential fixation of the wedge 4. Next, a torque wrench is inserted into the torque wrench insertion hole 231 of the power column 23, and the torque is applied by the torque wrench to drive the wedge 4 to rotate, so that the screw and the parking screw sleeve 33 can be threadedly tightened, and the wedge 4 can be quickly installed in the parking cylinder 3. Compared with the existing manual screwing installation of the wedge 4, the installation method of this embodiment is more efficient and saves time and effort.

[0065] The above is only an illustrative embodiment of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
