Description

Technical Field

[0001] The utility model relates to the technical field of a locomotive door air tightness test device, in particular to a door installation auxiliary structure used for a locomotive door air tightness test. Background Art

[0002] After the locomotive door is produced, the airtight structure of the door needs to be tested. That is, the door needs to be installed on the door frame of the box section to test the airtightness.

[0003] Since the car door has a certain weight, the traditional installation method for installing the car door on the door frame is to use a trolley to lift the car door, and then manually align the car door with the door frame little by little, and then fix the car door on the door frame. However, the disadvantage is that it is very difficult to manually align the car door with the door frame; specifically, since the car door is lifted, if it is aligned left and right, it is necessary to rotate the car door to a certain angle, and if it is aligned up and down, the trolley needs to be lifted or lowered; after the left and right and up and down positions are aligned, when the car door is pushed forward a small distance to fit the door frame completely and tightly, there will be an error in the height direction (the trolley position does not move, and the car door is pushed forward to fit the door frame, there is a slight displacement in the horizontal direction, so there is an error in the vertical direction), and this error is difficult to adjust with the trolley, so the alignment installation process is very difficult.

[0004] Based on this, our company has designed a tooling to assist in the installation of vehicle doors. Instead of using a trolley, the alignment is completed through this tooling, which is simpler, more convenient, and more precise. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provides a door installation auxiliary structure for a locomotive door air tightness test.

[0006] The purpose of the utility model is achieved through the following technical solutions: a door installation auxiliary structure for locomotive door air tightness test, comprising:

[0007] A support frame having an inclined surface, which is fixed to the bottom plate;

[0008] An ejection mechanism, which is mounted on the support frame;

[0009] The front part of the bottom plate is a placement part, and the inclined surface of the support frame is a support part;

[0010] Place the bottom of the door on the placement position, tilt the door against the supporting position, move the entire door installation auxiliary structure to the door frame of the locomotive door valve performance test box, shake the threaded rocker to let the ejection mechanism lift up from the back of the door, and change the door from a tilted state to a vertical state.

[0011] As a preferred technical solution of the present application, a detachable limit frame is also provided at the inclined surface of the support frame; when the vehicle door is tilted and leans against the supporting part, the limit frame limits the vehicle door to prevent the vehicle door from falling when the vehicle door moves with the entire vehicle door installation auxiliary structure.

[0012] As a preferred technical solution of the present application, the ejection mechanism is arranged at the upper and middle part of the upper and lower positions along the supporting surface; the ejection mechanism includes a top frame and a threaded rocker; the top frame is arranged close to the inclined surface, the front side of the top frame contacts the back side of the vehicle door, and a threaded rocker is fixed to the back side of the top frame, and the threaded rocker cooperates with the threaded hole on the support frame; when the threaded rocker is rotated, the top frame lifts up the back side of the vehicle door, allowing the vehicle door to change from an inclined state to a vertical state.

[0013] As a preferred technical solution of the present application, a sliding rod is also fixed to the back of the top frame, and a corresponding sliding hole is opened on the support frame. The sliding rod is inserted into the sliding hole to form a structure for placing the top frame to rotate.

[0014] As a preferred technical solution of the present application, the support frame is further provided with a rotatable cam at the middle and lower part along the height direction close to the inclined surface; when the cam rotates, different positions of its circumferential edge contact the back of the vehicle door, thereby pushing the lower part of the vehicle door forward.

[0015] As a preferred technical solution of the present application, the cam is rotated by a crank, and the crank is mounted on a support frame.

[0016] As a preferred technical solution of the present application, a roller that can be locked and released is provided at the placement position; when the vehicle door needs to be placed at an angle, the roller is locked and the bottom of the vehicle door is placed on the roller; when the vehicle door needs to be changed from a tilted state to a vertical state, the roller is released to facilitate the forward movement of the vehicle door.

[0017] As a preferred technical solution of the present application, a roller is arranged directly below the bottom plate, and a support mechanism capable of adjusting the height is also arranged on the bottom plate.

[0018] The general working principle of the utility model is:

[0019] The doors of locomotives need to be installed on a box section with a door frame for air tightness test, but the doors are heavy and it is difficult to align the doors with the door frame (currently the method is to lift the door with a crane and align it manually).

[0020] The operation method of this scheme is: a. Place the car door on the car door installation auxiliary mechanism in a tilted manner in advance, and then move the installation auxiliary mechanism to the door frame of the box section; b. Then apply force from the ejection mechanism from the back of the car door to lift the car door, so that the car door changes from a tilted state to a vertical state; c. Unlock the locking state of the roller, and then turn the cam, the cam rests on the middle and lower part of the car door, and the bottom of the car door gradually moves forward (and in this process, it is gradually ejected synchronously with the ejection mechanism); d. Finally, make the car door completely fit the door frame of the box section, complete the installation, and then conduct an air tightness test.

[0021] The utility model has the following advantages:

[0022] (1) It is simpler and more convenient to install the door on the door frame on the box section;

[0023] Compared with the method of lifting the door by a crane and then aligning the door with the door frame little by little manually, this solution uses the door installation auxiliary mechanism to erect the door little by little through the ejection mechanism, and can move the door forward little by little through the cam and roller, gradually approaching the door frame and aligning it with the door frame, which is simpler and more convenient to operate;

[0024] (2) Accurate position adjustment;

[0025] Compared with the method of aligning the car door with the door frame by people, this solution can adjust the left and right position of the car door relative to the door frame through rollers (the height of the door frame is fixed, so the height position of the car door and the door frame can be determined when designing the base plate and the roller; of course, it can also be adjusted through the supporting mechanism). The car door can be gradually brought closer to the door frame through the cam and the roller, and the vertical state of the car door can be adjusted through the lifting mechanism; this gradual adjustment method allows the car door and the door frame to be aligned more accurately.

[0037] This embodiment proposes a door installation auxiliary structure for locomotive door air tightness test, on which an inclined door can be placed, and then the door can be moved to the box section for air tightness test, so that the door and the door frame on the box section can be adjusted and aligned little by little, and finally the door can be accurately installed on the box section; the problem of inconvenient installation and difficult accurate alignment in the traditional installation method using a crane and manual alignment is solved.

[0038] (Example 1)

[0039] like Figure 1 As shown, the door installation auxiliary structure for the door air tightness test includes a support frame 1, a bottom plate 2, and an ejection mechanism 3; the support frame 1 is vertically fixed on the bottom plate 2, and the support frame 1 has an inclined surface, which is a supporting portion 101; the upper surface of the bottom plate 2 in front of the supporting portion 101 is a placement portion 201, that is, the bottom end of the supporting portion 101 is at a certain distance from the front end surface of the bottom plate 2, and the area between the bottom end of the supporting portion 101 and the front end of the bottom plate 2 on the bottom plate 2 is the placement portion 201;

[0040] An ejection mechanism 3 is also installed on the support frame 1. The ejection mechanism 3 is located in the upper middle part of the support frame 1 and is arranged close to the inclined surface.

[0041] When the door needs to be moved to the box joint, the bottom of the door is placed on the placement position 201, and the door is tilted against the support position 101; when the door needs to be aligned with the door frame of the box joint for installation, the ejection mechanism 3 is extended to the back of the door to change the door from a tilted state to a vertical state.

[0042] See also Figure 2 , the ejection mechanism 3 is designed. The ejection mechanism 3 is arranged at the middle and upper part of the upper and lower positions of the support surface, and includes a top frame 301 and a threaded rocker 302, wherein the top frame 301 is arranged close to the inclined surface, the front of the top frame 301 contacts the back of the door, and the back of the top frame 301 is fixed with a threaded rocker 302, and the threaded rocker 302 matches the threaded hole on the support frame 1;

[0043] A slide bar 303 is also fixed to the back of the top frame 301, and a corresponding slide hole is opened on the support frame 1, and the slide bar 303 is inserted into the slide hole to form a structure for placing the top frame 301 to rotate;

[0044] When the ejection mechanism 3 is working, the threaded rocker 302 is manually rotated, and the threaded rocker 302 pushes the top frame 301 forward, and the top frame 301 abuts against the back of the door, thereby changing the door from an inclined state to a vertical state.

[0045] In this embodiment, a roller is provided directly below the bottom plate 2, and a height-adjustable support mechanism (not shown in the figure) is also provided on the bottom plate 2. The entire auxiliary mounting structure is moved by the roller that can be locked. The support mechanism includes a threaded rod, which vertically passes through the bottom plate 2 and the two are threadedly matched. The lower end of the threaded rod has a pad foot, and the upper end of the threaded rod has a disc. The height adjustment of the support mechanism is achieved by rotating the disc.

[0046] (Example 2)

[0047] On the basis of embodiment 1, a structure is also designed to prevent the door from sliding off the two vehicles.

[0048] See also Figure 2 The top frame 301 is C-shaped to prevent the door from sliding off from both sides. Another C-shaped frame 102 is provided on the support frame 1 to also prevent the door from sliding off from both sides.

[0049] See also Figure 2 , a detachable limit frame 4 is also provided at the inclined surface of the support frame 1; the limit frame 4 is in a C-shaped frame shape, with plugs at both ends; plug holes are provided at both ends of the top frame 301; and pin holes are provided at the plug and the plug hole. During installation: insert the two ends of the limit frame 4 into the plug holes of the top frame 301, align the pin holes of the plug and the plug hole after insertion, and insert the pin 401 into the two pin holes, thus realizing the locking installation of the limit frame 4. In the process of moving the entire auxiliary installation structure to the box section, the door can be prevented from slipping.

[0050] (Example 3)

[0051] On the basis of Example 1 or Example 2, a corresponding structural design is also performed on the door frame close to the box section of the vehicle door.

[0052] See also Figure 3 , Figure 4 A plurality of rotatable cams 5 are provided at the middle and lower part of the support frame 1 in the height direction near the inclined surface; the cams 5 are mounted on the support frame 1 through a crank 501, and the cams 5 are against the back of the door;

[0053] In addition, at the placement position 201, a roller 6 that can be locked and released is provided;

[0054] When the car door is placed on the entire auxiliary mounting structure, the bottom of the car door is placed on the locked roller 6; when the car door needs to be gradually moved closer to the door frame on the box section, the roller 6 is unlocked and the cam 5 is gradually rotated by the crank 501. When the cam 5 rotates, it abuts against the lower part of the back of the car door, allowing the car door to gradually move closer to the door frame.

[0055] In this embodiment, a locking hole A601 is opened on the rotating shaft of the drum 6, and a locking hole B602 is opened on the bottom plate 2; when the locking piece 603 with two locking heads is correspondingly inserted into the locking hole A601 and the locking hole B602, the rotating drum 6 is locked; when the locking piece 7 is pulled out, the drum 6 is unlocked.

[0056] It should be noted that when the vehicle door installation auxiliary structure of the utility model is working:

[0057] Insert the locking head (in the shape of a prism) of the locking member 7 into the corresponding locking hole A601 and locking hole B602 to prevent the roller 6 from rotating; then use the crane to hang the door of the locomotive on the door installation auxiliary structure, when hanging, the bottom of the door is against the roller 6, and the door is inclined against the supporting part 101 (at this time, the ejection mechanism 3 is in a backward retracted state, and the cam 3 is not in contact with the back of the door);

[0058] Then, the plug of the limit frame 4 is inserted into the jack of the top frame 301, and the pin 401 is inserted into the corresponding pin hole, so that the limit frame 4 is fixed on the top frame 301; the top frame 301 and the limit frame 4 together surround the door to prevent the door from sliding off;

[0059] Move the entire door installation auxiliary mechanism to the box joint, and adjust the left and right positions of the door and the door frame on the box joint (realized by the rollers of the bottom plate 2); then extend the support mechanism to fix the position, and then adjust the height of the bottom plate 2 through the support mechanism, thereby adjusting the height position between the door and the door frame;

[0060] Then remove the limit frame 4, rotate the threaded rocker 302, the threaded rocker 302 drives the top frame 301 to move forward, the top frame 301 is against the middle and upper part of the back of the car door, so that the car door gradually changes from an inclined state to a vertical state; then remove the locking piece 7, the roller 6 can rotate, and shake the handle 501 to rotate the cam 5. Since the cam 5 has a shortest diameter and a longest diameter, when the cam 5 rotates, the edge between the shortest diameter and the longest diameter will contact the middle and lower part of the back of the car door. As the cam 5 rotates, it will exert a force on the car door forward, so that the lower part of the car door rolls on the roller 6 and gradually moves forward; under the action of the lifting mechanism 3 and the cam 5, the car door can gradually get closer to the door frame;

[0061] When the car door is close to the door frame, install the car door on the door frame, and then the air tightness test can be carried out on the box section.
