Description

Technical Field

[0001] The utility model relates to the technical field of railway construction auxiliary equipment, in particular to a transverse moving trolley for D-shaped girder. Background Technique

[0002] The structure of the D-shaped girder is mainly composed of two longitudinal girders and several cross girders. Specific models such as D16 type and D24 type are respectively provided with different numbers of cross girders. The D16 type is provided with 25 cross girders, while the D24 type is provided with 37 cross girders. In addition, the accessories of the D-shaped girder include brackets, gusset plates, diagonal bars, ballast retaining plates, positioning angle irons and special rail fasteners, and all components are connected by refined bolts.

[0003] When a highway passes under a railway and an overpass needs to be built or other buildings need to be added (rebuilt) on the existing line, in order not to affect the normal operation of the railway, and when it is not feasible or economical to detour, the D-shaped girder is often used to reinforce the line by overhead, and then open cut or jacking construction is carried out to complete the bridge construction. The technological principle of the D-shaped girder is to build temporary supports for the D-shaped girder on both sides of the existing line at the bridge position. After the temporary supports reach the design strength, the D-shaped girder is installed. The train passes through the existing line reinforced with the D-shaped girder at a speed limited to 45 Km / h, and then the subgrade bridge and culvert operation construction is carried out. After the bridge and culvert operation construction is completed, the girder is removed, the line is restored, and the train resumes normal speed operation.

[0004] The spacing setting of the D-shaped girder depends on the specific situation of the line, including factors such as line type (single track or double track), curve radius, line spacing and the layout form of the girder. For example, the spacing of the D24 type low-height construction girder is different in the case of single track and double track, and these dimensions are determined according to specific railway design and construction requirements. The existing beam transport vehicle cannot horizontally transport the girder perpendicular to the railway track according to the spacing of the D-shaped girder, and still needs to be adjusted manually, resulting in lower construction efficiency and greater handling difficulty. Content of the Utility Model

[0005] The purpose of the utility model is to solve the technical problems existing in the prior art, and provides a transverse moving trolley for D-shaped girder, which has a simple structure and is easy to operate, and can horizontally and laterally adjust the distance between the D-shaped girder and the railway center, improving the construction efficiency of the girder.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A D-shaped movable cross beam trolley, comprising two car bodies, the two car bodies are arranged side by side on the railway track and move along the length direction of the railway track. A single car body includes a frame and traveling wheels arranged at the bottom of the frame.

The telescopic directions of the two transverse telescopic mechanisms are arranged oppositely. A vertical frame is arranged on each of the two transverse telescopic mechanisms. A fixed plate is arranged on the vertical frame. A first support bracket is arranged on the fixed plate. The cross beams at both ends in the length direction of the D-shaped movable cross beam on both sides of the railway track are respectively connected to the two first support brackets of the front and rear car bodies.

When the two car bodies lift and hoist the D-shaped movable cross beam and run along the railway track direction, one car body is the driving trolley running along the railway, and the other car body is in a driven (powerless state). The driving car body is responsible for pulling the driven car body through the D-shaped movable cross beam to ensure that the two car bodies can operate coordinately and maintain a certain speed.

[0009] A further solution of the utility model lies in that the transverse telescopic mechanism includes a main arm, a telescopic arm and a telescopic hydraulic cylinder. The main arm is arranged across the two end beams and is fixedly connected to the end beams. The telescopic arm is sleeved inside the main arm and is slidably connected to the inside of the main arm. One end of the cylinder body of the telescopic hydraulic cylinder is connected to the main arm, and one end of the telescopic rod of the telescopic hydraulic cylinder is connected to the telescopic arm.

[0010] A further solution of the utility model lies in that both the main arm and the telescopic arm are square frames with hollow interiors, and the telescopic hydraulic cylinder is arranged inside the telescopic arm, realizing the light weight and compact structure of the trolley.

[0011] A further solution of the utility model lies in that guide rollers are arranged at the bottom of the telescopic arm. Specifically, the guide rollers are installed outside the bottom plate of the main arm, and part of the guide rollers pass through the bottom of the main arm and are placed inside the bottom plate of the main arm.

[0012] A further solution of the utility model lies in that a second support bracket is arranged on the fixed plate, which is applicable to the D-shaped movable cross beam of D24 model.

[0013] A further solution of the present utility model is that the first support bracket and the second support bracket are fixed on the fixed plate by bolts.

[0014] A further solution of the present utility model is that the first support bracket and the second support bracket include two clamping plates, and the cross beam of the D-shaped temporary beam is placed between the two clamping plates and fixed by bolts passing through the clamping plates and the cross beam in sequence.

[0015] A further solution of the present utility model is that hydraulic legs are also provided at the four corner ends of the vehicle body.

[0027] As Figure 1 、 Figure 5 As shown, a D-shaped movable bogie for lateral movement includes two car bodies 1. The two car bodies 1 are arranged side by side on the railway track 6 and travel along the length direction of the railway track 6. Each individual car body 1 includes a frame and traveling wheels 12 provided at the bottom of the frame.

[0028] A further aspect of the present utility model is that the frame includes two end beams. At both ends of the bottom of the two end beams, there is one traveling wheel 12 each, and the motor is connected to any one of the traveling wheels 12 through a reducer.

[0029] The two car bodies 1 and the D-shaped beams 7 on both sides together form a bogie. The car body 1 with a motor is connected to the other car body 1 through the D-shaped beam 7. When the two car bodies 1 lift and move the D-shaped beam 7 along the direction of the railway track 6, one car body 1 is the driving bogie traveling along the railway, and the other car body 1 is in a driven (powerless) state. The driving car body 1 is responsible for pulling the driven car body 1 through the D-shaped beam 7 to ensure that the two car bodies 1 can operate coordinately and maintain a certain speed.

[0030] As Figure 3 As shown, two lateral telescopic mechanisms are arranged at intervals along the length direction of the frame on the frame. The telescopic directions of the two lateral telescopic mechanisms are arranged oppositely. On each of the two lateral telescopic mechanisms, there is an upright frame 4. On the upright frame 4, there is a fixed plate 5. On the fixed plate 5, there is a first support bracket 8. It is applicable to the D-shaped beam 7 of the D16 model. On the fixed plate 5, there is a second support bracket 9, which is applicable to the D-shaped beam 7 of the D24 model. The cross beams at both ends of the length direction of the D-shaped beams 7 on both sides of the railway track 6 are respectively connected to the two first support brackets 8 of the front and rear two car bodies 1.

[0031] A further aspect of the present utility model is that, as Figure 4As shown, the horizontal telescopic mechanism includes a main arm 2, a telescopic arm 3, and a telescopic hydraulic cylinder 10. The main arm 2 is horizontally arranged across two end beams and fixedly connected to the end beams. The telescopic arm 3 is sleeved inside the main arm 2 and slidably connected to the inside of the main arm 2. One end of the cylinder body of the telescopic hydraulic cylinder 10 is connected to the main arm 2, and one end of the telescopic rod of the telescopic hydraulic cylinder 10 is connected to the telescopic arm 3. The telescopic hydraulic cylinder 10 drives the telescopic arm 3 to reciprocate horizontally along the main arm 2.

[0032] A further solution of the present utility model is that both the main arm 2 and the telescopic arm 3 are square frames with hollow interiors, and the telescopic hydraulic cylinder 10 is arranged inside the telescopic arm 3 to achieve the light weight and compact structure of the trolley.

[0033] A further solution of the present utility model is that guide rollers 11 are provided at the bottom of the telescopic arm 3. Specifically, the guide rollers 11 are installed outside the bottom plate of the main arm 2, and part of the guide rollers 11 passes through the bottom of the main arm 2 and is placed inside the bottom plate of the main arm 2, and the bottom plate of the telescopic arm 3 contacts the guide rollers 11. Guide rollers 11 are also provided on both sides of the telescopic arm 3.

[0034] A further solution of the present utility model is that the first support bracket 8 and the second support bracket 9 are fixed to the fixing plate 5 by bolts. The first support bracket 8 and the second support bracket 9 include two clamping plates, and the cross beam of the D-shaped temporary beam 7 is placed between the two clamping plates and fixed by bolts passing through the clamping plates and the cross beam in sequence.

[0035] A further solution of the present utility model is that hydraulic legs are also provided at the four corner ends of the vehicle body. This enables the temporary beam to maintain force balance during lateral movement and makes it less likely for the vehicle frame to tip over.

[0036] The present utility model realizes the lateral expansion and contraction of the upright frame 4 in the direction perpendicular to the railway track 6 through the telescopic arm 3 of the horizontal telescopic mechanism, meeting the construction requirements for hoisting the D-shaped temporary beam 7 at different line spacings of the railway track 6. Its structure is simple and easy to operate, suitable for different spacings of the D-shaped temporary beam 7, and improves the construction efficiency of the temporary beam.

[0037] Usage steps:

[0038] (1) Place the D-shaped temporary beam 7 on the open spaces on both sides of the railway track 6 by a crane. As Figure 5 shown, erect this trolley along the length direction of the railway track 6. The two vehicle bodies 1 are arranged at intervals front and back, and the distance between the head and the tail of the two vehicle bodies 1 is less than the length of the D-shaped temporary beam 7;

[0039] (2) As Figure 1As shown in the figure, the D-shaped beams 7 on both sides are installed on the fixing plates 5 of the two car bodies 1 with the help of a lifting tool manually. The cross beams of the D-shaped beams 7 are fixed on the first support bracket 8 (applicable to D16) or the second support bracket 9 (applicable to D24). The D-shaped beams 7 on both sides should be installed simultaneously. Lift the D-shaped beams 7 of the same model on both sides to ensure the balanced force on both sides of the sliding trolley and avoid tipping over.

[0040] (3) As Figure 1 shown in the figure, after the installation is completed, start the motor, and the D-shaped beam 7 can be longitudinally moved along the length direction of the railway track 6. The traveling speed of the car body 1 is not greater than 5 m / min. When the two car bodies 1 lift and hoist the D-shaped beam 7 and travel along the direction of the railway track 6, one car body 1 provides driving force for traveling, and the other transfer trolley is in a driven (powerless state) state after releasing the brake. The driving car body 1 is responsible for pulling and guiding the trailing car body 1 to ensure that the two car bodies 1 can travel synchronously, ensuring construction efficiency and safety.

[0041] (4) As Figures 2-4 shown in the figure, after reaching the required construction position, adjust the telescopic length of the telescopic arm 3 according to the spacing of the D-shaped beam 7, and manually install and fix the D-shaped beam 7.
