Description

Technical Field

[0001] The utility model specifically relates to a bogie limiting device. Background Art

[0002] During the inspection and maintenance of railway freight cars, the disassembly and assembly of the bogies of railway freight cars will involve a large number of stopping operations. The existing bogie stopping operation methods are mostly manual operations, that is, manually using wheel stop wedges for limiting, specifically: first, the worker observes that the bogie has reached the specified position, and the worker takes a manual stopping tool (wheel stop wedge) and places it on the front rail surface of the bogie wheel. The bogie is blocked by the wheel stop wedge and stops. At this time, the worker takes another stopping tool (wheel stop wedge) and places it on the rear rail surface of the bogie wheel. After the bogie rebounds, it is blocked by the rear stopping tool. In this way, the bogie bounces several times between the two stopping tools and stops, and finally stops in the middle position.

[0003] The above-mentioned method of manually stopping the bogie has the following defects: (1) the stopping tool is placed manually, and the stopping error is large; (2) when a large number of bogies are in production, the operator needs to maintain a high degree of concentration, otherwise collisions are likely to occur, causing damage to the operator or equipment such as the bogie; (3) manual tool stopping cannot meet the needs of automated production, and the manual stopping requires the collaboration of two people. Summary of the invention

[0004] In view of the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a bogie limiting device.

[0005] The technical solution adopted by the utility model is:

[0006] A bogie limiting device comprises a support seat and a fixed seat, an oblique brace, a fixed shaft, a rubber wedge, a guide rail, a cylinder and a rubber wedge fixing plate arranged on the support seat; the fixed seat is fixedly connected to the support seat and the fixed seat is locked and fixed on the inner side of the track; two oblique braces are symmetrically arranged on the support seat; the cylinder is connected to the rubber wedge fixing plate, the rubber wedge fixing plate and the guide rail slide against each other and the rubber wedge fixing plate is connected to the rubber wedge; the rubber wedge is located below the oblique brace, and the oblique brace rotates and rises and falls around the fixed shaft fixed on the support seat.

[0007] Furthermore, the two cylinders move independently of each other.

[0008] Furthermore, the bogie limiting devices are installed on the track in pairs.

[0009] Furthermore, a protective cover is provided on the support seat, and the protective cover shields the rubber wedge, the guide rail, the cylinder, and the rubber wedge fixing plate from the side of the fixing seat, and the protective cover cannot shield the diagonal brace.

[0010] Furthermore, a set of guide rails are installed on the upper and lower surfaces of the support seat respectively, and a rubber wedge fixing plate is installed on the slider of the guide rail above the support seat, and the rubber wedge fixing plate is connected to a rubber wedge, thereby driving the diagonal brace to rise and fall; another rubber wedge fixing plate is installed on the slider of the guide rail below the support seat, and the rubber wedge fixing plate is connected to another rubber wedge, thereby driving the other diagonal brace to rise and fall.

[0011] Furthermore, a set of guide rails are installed on each side of the support seat, and a rubber wedge fixing plate is installed on the slider of the guide rail on one side of the support seat, and the rubber wedge fixing plate is connected to a rubber wedge, thereby driving the diagonal brace to rise and fall; another rubber wedge fixing plate is installed on the slider of the guide rail on the other side of the support seat, and the rubber wedge fixing plate is connected to another rubber wedge, thereby driving the other diagonal brace to rise and fall.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Reference Figure 2 As shown, the bogie limiting device B of this embodiment includes a diagonal support 2, a rubber wedge 3, a fixing plate 4, a support seat 5, a ball guide 6, a cylinder 7, a first rubber wedge fixing plate 8, a connecting member 9, a fixing shaft 10, and a second rubber wedge fixing plate 11;

[0027] Among them, the fixing plate 4 is arranged vertically, and the fixing plate 4 is locked and fixed on the inner side of the track A, so that the entire bogie limiting device B is locked and fixed on the inner side of the track A (the fixed position here is the inner side of the track A, because the wheel flange of the wheelset is on the inner side of the track, and the bogie limiting device B of this embodiment is used to limit the wheel flange). Figure 1 shown.

[0028] The support seat 5 and the fixed plate 4 are fixedly connected, with the support seat 5 as a base, and the support seat 5 is provided with the above-mentioned diagonal support 2, rubber wedge 3, ball guide rail 6, cylinder 7, first rubber wedge fixed plate 8, connecting piece 9, fixed shaft 10, and second rubber wedge fixed plate 11.

[0029] Two diagonal braces 2 are symmetrically arranged on the support seat 5 . The diagonal braces 2 can rotate at an angle of about 30° around a fixed shaft 10 , and the fixed shaft 10 is fixed on the support seat 5 .

[0030] Preferably, a wear-resistant plate 1 is installed on the upper surface of the diagonal support 2, which can effectively reduce the wear of the workpiece.

[0031] The lower surface of the diagonal support 2 is configured as an arc-shaped structure to facilitate contact and sliding with the rubber wedge 3 .

[0032] For a single diagonal brace 2, a ball guide rail 6 is provided in the length direction of the support seat 5, that is, the setting direction of the diagonal brace 2. A slider is provided on the ball guide rail 6, and a rubber wedge fixing plate is fixed on the slider. The side of the rubber wedge fixing plate is fixedly connected to the rubber wedge 3, and the rubber wedge 3 is movably installed under the diagonal brace 2; a connecting piece 9 is also connected to the top of the rubber wedge fixing plate, and the connecting piece 9 is connected to the telescopic end of the cylinder 7. The fixed end of the cylinder 7 is fixed on the support seat 5. The cylinder 7 telescopes and moves, and drives the rubber wedge fixing plate to move horizontally through the connecting piece 9, thereby driving the rubber wedge 3 to move horizontally under the diagonal brace 2, and the non-fixed end of the diagonal brace 2 rises and falls at a certain angle.

[0033] The two cylinders 7 can move independently of each other, so as to meet the flexible operation function of lifting and lowering the two diagonal supports 2 separately or synchronously.

[0034] like Figure 3 As shown, in this embodiment, a set of ball guide rails 6 are installed on the upper and lower surfaces of the support seat 5, and a first rubber wedge fixing plate 8 is installed on the slider of the ball guide rail 6 above the support seat 5. The first rubber wedge fixing plate 8 is connected Figure 3 The rubber wedge 3 on the right side drives Figure 3 The right side brace 2 is lifted and lowered. A second rubber wedge fixing plate 11 is installed on the slider of the ball guide rail 6 below the support seat 5. The second rubber wedge fixing plate 11 is connected to Figure 3 The rubber wedge 3 on the left side drives Figure 3 The diagonal brace 2 on the left side rises and falls.

[0035] Of course, a set of ball guide rails 6 can also be provided on both sides of the support seat 5 in the length direction, and a first rubber wedge fixing plate 8 is installed on the slider of the ball guide rail 6 on one side of the support seat 5. Figure 3 The rubber wedge 3 on the right side drives Figure 3 The right side diagonal support 2 is lifted. A second rubber wedge fixing plate 11 is installed on the slider of the ball guide rail 6 on the other side of the support seat 5. The second rubber wedge fixing plate 11 is connected to Figure 3 The rubber wedge 3 on the left side drives Figure 3 The diagonal brace 2 on the left side rises and falls.

[0036] That is, there is no specific limitation on the arrangement positions of the ball guide rail 6 and the matching slider, cylinder 7, etc., as long as the two diagonal supports 2 can be lifted or lowered.

[0037] like Figure 4 As shown, a protective cover 12 is disposed on the support seat 5 , and the protective cover 12 is located on the opposite side of the fixing plate 12 , and the protective cover 12 cannot block the diagonal brace 12 .

[0038] The protective cover 12 serves as a safety protection to prevent personnel from accidentally touching the cylinder 7 and the transmission mechanism (such as the rubber wedge fixing plate, the connector 9, and the ball guide 6) in operation and causing accidents. The bogie limit device B can be used underground or in a pit. The pit type is more common in the rail industry. Sometimes personnel check the bogie D under the track A, which can easily cause the personnel's limbs to come into contact with the transmission mechanism. In this case, the protective cover 12 is necessary. The underground buried type can also prevent leakage from the upper part of the bogie limit device B, accidents caused by human contact, or damage to the mechanism caused by other objects entering. Due to the large assembly error of the bogie D, it is preferred to position only the front wheels or only the rear wheels. If Figure 1 As shown, two bogie limit devices B are installed on the track A, and opposing in-place detection switches C are installed on both sides of the track A to detect whether the wheels of the bogie D are in place; the two wheels of the same axle of the bogie D are limited simultaneously by the two bogie limit devices B, so that the force of the bogie D is more balanced and the state is more stable.

[0039] like Figure 2 As shown, it is a schematic diagram of the limiting state of the bogie limiting device B. It can be seen that the two diagonal supports 2 of the bogie limiting device B are raised to form a V-shaped structure to limit the wheelset of the bogie D.

[0040] When the bogie D is pushed over from somewhere else, the two sides of the V-shaped structure of the bogie limit device B (i.e., the two diagonal struts 2) are respectively in the state of waiting for raising and waiting for raising; when the bogie D is pushed to the position of the bogie limit device B, the raised part of the front V-shaped structure (i.e., a raised diagonal strut 2) acts as a limit and block for the bogie D, and at this time the wheel triggers the in-place detection switch C, and at this time the waiting-to-raise part of the V-shaped structure (i.e., the other diagonal strut 2) rises, and the two diagonal struts 2 form a V-shaped structure to limit the wheels of the bogie D.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute a limitation on the protection scope of the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
