Description

Technical Field

[0001] The present application relates to the technical field of rail vehicles, and in particular to a method for installing a mechanical brake track. Background Art

[0002] At present, there is generally a trailer system for carrying ship models across the top of the ship test pool. With the progress of the times, the research on ships has become more in-depth, and the speed of ships has gradually exceeded. In order to ensure the safety of high-speed test trailers, in the event of control and braking failure of the test trailer, the trailer can be effectively stopped when it reaches the end of the pool. Braking devices are usually installed to brake the trailer in emergency situations or special requirements.

[0003] In the related art, in order to avoid safety hazards caused by the sudden failure of the brake device of the test trailer or the inability to slow down and stop when the electronic control fails, a track used solely for braking is set up, and a brake unit is provided on the track. When the brake block of the trailer hits the brake unit, the vehicle will drive the brake unit to slide relative to the track in turn. Due to the friction between the brake unit and the track, the braking force of the vehicle is gradually increased, and the vehicle is finally braked and stopped. Since this kind of mechanical brake track has high precision requirements and needs to be installed completely at the project site, its installation accuracy needs to be controlled. However, the current installation often affects the overall accuracy of the track due to welding deformation, and many auxiliary positioning devices need to be used, which has high requirements on construction equipment, and the entire construction process is time-consuming and labor-intensive.

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] The embodiment of the present application provides a method for installing a mechanical brake track, which can solve the problems in the related art that the track used for braking is deformed by welding during installation, affecting the overall accuracy of the track, requiring the use of many auxiliary positioning devices, placing high requirements on construction equipment, and the entire construction process is time-consuming and labor-intensive.

[0049] See also Figure 1As shown, the installation method first fixes two T-shaped guide rails 1 to multiple pads 2 respectively, so that the two T-shaped guide rails 1 are respectively connected and fixed to the corresponding pads 2 to form an integral structure, and then the overall structure is moved as a whole, and the multiple pads 2 on it are respectively preliminarily fixed to the embedded bottom plate 3 to form an initial track, and then multiple brake units 4 are installed on the initial track in sequence, and the fixing characteristics of the brake units 4 themselves are used to provide suitable rigid fixing constraints so that the multiple brake units 4 are arranged side by side, and the width weld 20 along the thickness direction and the outer side weld 21 along the length direction of each pad 2 installed with the brake unit 4 are welded, and the multiple brake units 4 are moved along the initial track in sequence to ensure that during welding, there are rigid fixing constraints on the corresponding initial track segments, which can effectively avoid welding deformation and ensure accuracy, and repeat the operation of this step to ensure that the width welds 20 and outer side welds 21 of all pads 2 are welded Then, similarly, multiple brake units 4 are sequentially installed on the initial track, so that multiple brake units 4 are arranged at intervals, and the inner weld 22 of each pad 2 located between the first and last brake units 4 along the length direction is welded, and multiple brake units 4 are sequentially moved along the initial track, and the operation of this step is repeated to weld the inner welds 22 of all pads 2. Since the width of the initial track is relatively small, the operating space is very limited during installation. Therefore, multiple brake units 4 are arranged at intervals when welding the inner weld 22, so that the welding head can be extended into the inner weld 22 through the vacant position next to it during welding. In addition, when welding the inner weld 22, since the outer weld 21 and the width weld 20 have been welded, the overall position of the initial track is basically fixed at this time. Even if the brake units 4 are arranged at intervals when welding the inner weld 22, sufficient rigid fixed constraints can be provided. Finally, after all welding work is completed, all brake units 4 are sequentially installed side by side on the initial track according to the braking requirements to complete the installation of the mechanical brake track. This installation method uses the brake unit 4 as a positioning structure during installation, provides a suitable rigid fixing constraint, greatly reduces welding deformation during installation, ensures the accuracy of the mechanical brake track, and a reasonable welding sequence also simplifies the process.

[0050] For further information, see Figure 2 As shown, the steps before welding the width weld 20 and the outer weld 21 of the pad 2 also include: installing multiple brake units 4 in sequence on the initial track, so that the multiple brake units 4 are arranged side by side, and installing auxiliary ribs 5 connected to the embedded bottom plate 3 on the outer side of each pad 2 installed with the brake units 4, and moving the multiple brake units 4 along the initial track in sequence, and repeating the operation of this step so that the outer sides of all pads 2 are installed with auxiliary ribs 5.

[0051] Specifically, although a plurality of brake units 4 are arranged on the initial track before welding the width weld 20 and the outer weld 21 of the pad 2 to provide suitable rigid fixed constraints to prevent welding deformation, the connection between the brake unit 4 and the initial track is a movable connection, and under the action of a sufficiently large external force, movement may still occur. Therefore, before welding the width weld 20 and the outer weld 21 of the pad 2, auxiliary ribs 5 are sequentially installed on the outer sides of all pads 2, which can effectively prevent the pad 2 from being deformed during welding or being displaced due to external construction forces. The auxiliary ribs 5 are also connected and fixed to the pad 2 and the embedded base plate 3 by welding. Therefore, when installing the auxiliary ribs 5, the brake units 4 are also used for positioning. The setting method of the brake units 4 is consistent with the setting method when welding the width weld 20 and the outer weld 21 of the pad 2. The auxiliary rib plate 5 is a plate-like structure, and one side thereof connected to the pad 2 and the embedded bottom plate 3 is a right-angle structure, and the structures of other parts can be any suitable shape. Since the number of auxiliary rib plates 5 is relatively large, in order to avoid accidental injury to operators by the outer top angle of the auxiliary rib plate 5, preferably, the top angle of the upper outer side of the auxiliary rib plate 5 is generally cut to form a structure similar to an obtuse angle.

[0052] Furthermore, the specific steps of moving the multiple brake units 4 in sequence along the initial track include: first keeping at least one brake unit 4 currently close to the tail end stationary, and then moving the remaining brake units 4 in sequence to the empty initial track on one side of the brake unit 4 that remains stationary.

[0053] Specifically, since the length of the initial track used for braking is calculated based on the braking situation, the overall length is limited, and the initial track includes a starting end and a tail end. Therefore, when the brake unit 4 is installed on the initial track for the first time, it is generally started from the starting end, taking the starting end as the left end as an example, and the brake units 4 are installed in sequence from left to right. When the installation process of the initial track of this section is completed, at least one brake unit 4 close to the tail end is kept stationary, and the remaining brake units 4 are moved in sequence to the empty initial track on the right side of the brake unit 4 that remains stationary, and the previous arrangement is maintained. Specifically, the brake unit 4 to be moved is withdrawn from the starting end on the left, and then slides into the track from the tail end on the right. Here, the number of the brake units 4 that remain stationary can be one or more. In the present embodiment, when installing the auxiliary rib plate 5 and welding the width weld 20 and the outer weld 21 of the pad 2, since the overall positioning of the initial track is not very stable, the number of the brake units 4 that remain stationary can be three. When welding the inner weld 22 of the pad 2, since the overall positioning of the initial track is already relatively stable, the number of the brake units 4 that remain stationary can be one.

[0054] For further information, see Figure 4As shown, after auxiliary ribs 5 are installed on the outer sides of all pads 2, it also includes: installing multiple auxiliary fixing clamps 6 in sequence on the initial track, so that each auxiliary fixing clamp 6 is straddled between two T-shaped guide rails 1 to fix the distance between the tops of the two T-shaped guide rails 1.

[0055] Specifically, since the T-shaped guide rail 1 has a certain height, the auxiliary rib 5 is mainly used for limiting and fixing the bottom. In order to ensure the overall accuracy, a plurality of auxiliary fixing clamps 6 are installed in sequence on the initial track. The auxiliary fixing clamps 6 specifically include a clamp body 60. The clamp body 60 is U-shaped, and symmetrically arranged clamping arms 61 are respectively provided on the inner walls on both sides. A receiving area for accommodating the T-shaped guide rail 1 is formed between the clamping arms 61 and the side walls of the clamp body 60. In addition, fasteners 62 are symmetrically provided on the clamping arms 61 and the side walls of the clamp body 60. The fasteners 62 at least partially extend into the receiving area, and the length of the fasteners extending into the receiving area can be adjusted to achieve clamping and fixation of the T-shaped guide rail 1. During the actual construction, the clamp body 60 is placed across the two T-shaped guide rails 1, and the two T-shaped guide rails 1 are respectively accommodated in the accommodating areas, and then the fasteners 62 are adjusted so that the fasteners 62 on both sides clamp and fix the side walls of the T-shaped guide rails 1 to fix the distance between the tops of the two T-shaped guide rails 1, thereby ensuring the overall accuracy of the initial track.

[0056] For further information, see Figure 1 , Figure 6 and Figure 7 As shown, the specific steps of fixing the two T-shaped guide rails 1 to the plurality of pads 2 respectively, and preliminarily fixing the plurality of pads 2 to the embedded bottom plate 3 respectively to form the initial track include:

[0057] Sequentially determine the pad edge line 23 and the T-shaped guide rail edge line 10 on the embedded base plate 3;

[0058] The height of the top of the embedded bottom plate 3 is measured, and a plurality of pads 2 with different heights are manufactured according to the measurement result;

[0059] Place multiple pads 2 symmetrically on the preset bottom plate according to the pad edge line 23, place two T-shaped guide rails 1 on the pads 2 on the corresponding sides according to the edge line of the T-shaped guide rails 1, spot weld the two T-shaped guide rails 1 to the corresponding pads 2, and then weld the welds between the two T-shaped guide rails 1 and the corresponding pads 2;

[0060] A plurality of pads 2 welded and fixed to the corresponding T-shaped guide rails 1 are respectively spot-welded and fixed to the embedded bottom plate 3 to form an initial track.

[0061] Specifically, measurement and marking are first performed, and the pad edge line 23 and the T-shaped guide rail edge line 10 are determined in turn on the embedded base plate 3. There are two pad edge lines 23 and two T-shaped guide rail edge lines 10. The pad edge line 23 refers to the alignment line between the outer side of the pad 2 and the embedded base plate 3, and the T-shaped guide rail edge line 10 refers to the position of the adjacent side surface of the horizontal guide surface of the T-shaped guide rail 1. In addition, the center line 30 of the embedded base plate 3 itself will also be determined. Subsequently, construction measurements are carried out. Since the embedded base plate 3 is cast in advance by civil construction, and the accuracy deviation of civil construction is large, it is necessary to re-measure the height of the top of the embedded base plate 3, and make multiple pads 2 with different heights based on the measurement results to ensure that the working surface 11 of the T-shaped guide rail 1 set on the embedded base plate 3 is as close to the same horizontal plane as possible. Then, the initial installation is carried out, and the multiple pads 2 of different heights are positioned on the embedded base plate 3 using the pad edge line 23, and then the two T-shaped guide rails 1 are placed on the pads 2 on the corresponding side according to the T-shaped guide rail edge line 10. After this step, it is necessary to measure the flatness of the working surface 11 of the T-shaped guide rail 1 again. If it does not meet the construction requirements, a thin iron sheet is added between the corresponding pad 2 and the embedded steel plate to adjust the overall flatness of the working surface 11 of the T-shaped guide rail 1. Finally, a positioning is performed first, and the two T-shaped guide rails 1 are spot welded to the corresponding pads 2 respectively to achieve preliminary fixation. After spot welding, the welds between the two T-shaped guide rails 1 and the corresponding pads 2 are welded and fixed respectively; then a secondary fixation is performed, and the multiple pads 2 welded and fixed to the corresponding T-shaped guide rails 1 are spot welded and fixed to the embedded base plate 3 respectively to form an initial track.

[0062] For further information, see Figures 1 to 3 As shown, the step of sequentially installing a plurality of brake units 4 on the initial track specifically includes:

[0063] The brake unit 4 includes two brake plates 40, two limiting wheels 41 and two connecting members 42;

[0064] One of the brake plates 40 is attached to the bottom of the horizontal guide rail surfaces of the two T-shaped guide rails 1, and two limiting wheels 41 are separated and arranged on the brake plate 40, so that the two limiting wheels 41 are located between the two horizontal guide rail surfaces;

[0065] Another limiting wheel 41 is arranged outside each of the two limiting wheels 41, so that the two limiting wheels 41 located outside are also located between the two horizontal guide rail surfaces, and auxiliary gaskets 46 are sandwiched between the two limiting wheels 41 located outside and the horizontal guide rail surfaces;

[0066] The remaining brake plate 40 is arranged on the top of the horizontal guide rail surface of the two T-shaped guide rails 1, and two connecting members 42 are respectively passed through the brake plate 40 and the two limiting wheels 41 located on the inner side, so that the two brake plates 40 can be slidably clamped on the horizontal guide rail surface to fix the distance between the two T-shaped guide rails 1;

[0067] The above operation is repeated until a plurality of brake units 4 are installed on the initial track.

[0068] Specifically, since the track will shrink as a whole during the cooling process after welding, in order to avoid the overall reduction of the distance between the T-shaped guide rails 1 due to cooling shrinkage after welding, making it difficult to install the subsequent brake unit 4, two limiting wheels 41 are added when the brake unit 4 is used for positioning. The two limiting wheels 41 are arranged on the outside of the limiting wheels 41 of the brake unit 4, and an auxiliary gasket 46 is added between the limiting wheels 41 and the horizontal guide surface. The auxiliary gasket 46 is sandwiched between the limiting wheels 41 and the horizontal guide surface. Therefore, when the brake unit 4 is used for positioning, the distance between the T-shaped guide rails 1 is further increased. When the subsequent weld is cooled, the shrinkage amount can just balance the current increase, so that the track after welding can be smoothly installed with the brake unit 4. In addition, when the brake unit 4 is used to provide positioning, not all structures of the brake unit 4 are used, and only structures such as the brake plate 40, the limiting wheel 41, the connecting member 42 and the adjusting plate 43 arranged on the connecting member 42 are used.

[0069] Furthermore, the step before installing the auxiliary rib 5 connected to the embedded base plate 3 on the outer side of each pad 2 installed with the brake unit 4 also includes: cutting one of the top corners of the auxiliary rib 5 so that there is an operating gap 50 between the auxiliary rib 5 and the pad 2 and the embedded base plate 3.

[0070] Specifically, since the auxiliary rib plate 5 needs to be welded to the pad 2 and the embedded bottom plate 3 at the same time when being fixed, in order to prevent the auxiliary rib plate 5 from interfering with the welding of the outer weld 21, one of the top corners of the auxiliary rib plate 5 is cut so that there is an operating gap 50 between the auxiliary rib plate 5 and the pad 2 and the embedded bottom plate 3. The cutting shape here can be square or circular. In this embodiment, it is preferably circular. The operating gap 50 can ensure the welding of the outer weld 21.

[0071] Furthermore, before moving the multiple brake units 4 along the initial track in sequence, it is necessary to wait for at least a preset time until the welds between the pad 2 and the embedded bottom plate 3 are cooled. Specifically, since the temperature of the weld is high after welding, the structural strength is relatively low at this time. Therefore, after each welding is completed, it is necessary to wait for about 24 hours before performing subsequent welding work to ensure the overall structural accuracy.

[0072] For further information, see Figure 5 As shown, the steps before sequentially installing a plurality of brake units 4 on the initial track also include:

[0073] A plurality of auxiliary mounting bases 7 are provided at intervals at the bottom of the horizontal guide surface of each T-shaped guide rail 1;

[0074] Copper strips 44 are provided at the bottom and top of the horizontal guide surface of each T-shaped guide rail 1;

[0075] Rivets 45 are provided on the copper strip 44 and the horizontal guide rail surface so that the top of the auxiliary mounting base 7 abuts against the bottom of the rivet 45 , and the rivet 45 is hammered to fix the copper strip 44 to the horizontal guide rail surface.

[0076] Specifically, since the brake unit 4 needs to provide rigid fixed constraints during the early installation, the brake unit 4 needs to be frequently moved on the track. In order to ensure the smooth progress of the construction, before installing multiple brake units 4 on the initial track in sequence, the auxiliary mounting base 7 will be used to install the rivet 45 between the copper bar 44 and the T-shaped guide rail 1, and all the copper bars 44 will be fixed to the T-shaped guide rail 1 from one side to the other side in sequence using the rivet 45. The auxiliary mounting base 7 is arranged below the working surface 11 of the horizontal guide rail surface during construction, and it mainly plays a supporting role. When the rivet 45 is struck with a suitable striking tool such as a hammer, the auxiliary mounting base 7 can provide good support and fixation.

[0077] Furthermore, before all the brake units 4 are sequentially installed on the initial track, the auxiliary ribs 5 and the auxiliary fixing fixtures 6 are sequentially removed. Specifically, after welding is completed, the auxiliary fixing fixtures 6 are first removed, and the auxiliary ribs 5 may or may not be removed. In this embodiment, the auxiliary ribs 5 are directly cut off with a cutting tool.
