Description

Technical Field

[0001] The utility model relates to the field of shield construction machinery and equipment, in particular to a shield segment transport vehicle platform. Background Art

[0002] During shield tunnel construction, the various fuels, grouting materials and other consumables required for the shield machine are usually placed on the segment vehicles behind the marshaling group for transportation. The specific process is as follows:

[0003] 1) The consumables loading process mainly includes the following three steps:

[0004] 1-1. The gantry crane hoists various oils, bentonite and other consumables onto the segment truck at the wellhead;

[0005] 1-2. After the consumables are hoisted underground, the construction crane signal wire worker climbs onto the segment car and places the materials on the segments;

[0006] 1-3. Simply secure the material with straps or ropes;

[0007] 2) Transportation process: After loading is completed, the construction crane signal wire rope worker will check the material status and issue the departure order after confirming that it is correct until the vehicle enters the trolley to receive the vehicle;

[0008] 3) The vehicle pick-up process mainly includes the following two steps:

[0009] 3-1. After the marshaling group enters the trolley and arrives at the location, the person responsible for unloading the materials climbs onto the pipe segment and loosens the straps or ropes that secure the materials;

[0010] 3-2. Use the small sling inside the trolley to lift the oil to the vicinity of the grease pump, and other materials need to be manually assisted by the double-track beam for unloading.

[0011] In general, the current conventional method of transporting oil is to place the material on the segments of the segment truck. This method of transportation has great safety hazards. The segments and oil drums are round, and the oil drums are generally not fixed, which poses a risk of falling. The specific problems are as follows:

[0012] 1) Fuel or other materials are not fixed during transportation, and the train will shake during operation. Materials are likely to fall from the train and injure people or damage the track transportation system, resulting in work stoppage and production suspension;

[0013] 2) The segment truck is relatively high, and manual climbing is required when loading and unloading materials, which poses a safety hazard.

[0014] How to develop a new shield segment transport vehicle platform to achieve separate and stable transportation of various types of oil, bentonite and other consumables has become a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0015] The purpose of the utility model is to provide a shield segment transport vehicle platform to solve the problem that various consumables such as oil and bentonite are stacked on the segments during transportation, which may cause the risk of falling and potential safety hazards.

[0018] Preferably, side baffles are fixedly connected to three sides of the top surface of the anti-slip panel.

[0019] Preferably, the anti-slip panel is welded or fastened to the load-bearing frame by bolts.

[0020] Preferably, the anti-slip panel is set to a single plate structure or a composite plate structure. When set to a single plate structure, a fish pattern plate is used. When set to a composite plate structure, the bottom plate is a flat metal plate, and a layer of rubber plate is connected to the top surface of the flat metal plate.

[0021] Preferably, the load-bearing frame is formed by welding a plurality of steel sections together to form a square frame.

[0022] Preferably, two or four bottom support beams are provided at the bottom of the load-bearing frame, and the bottom support beams are symmetrically arranged.

[0023] Preferably, one side of the load-bearing frame is welded to the rear side of the segment car, and a diagonal bracing beam for reinforcement is provided between the bottom surface of the load-bearing frame and the side wall of the segment car; the other side of the load-bearing frame is connected to a connecting ear, and the connecting ear is detachably connected to the next segment car through a pin shaft.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] like Figure 1-4 As shown, a shield segment transport vehicle platform includes a load-bearing frame 1 and an anti-slip panel 2. The anti-slip panel 2 is positioned and connected to the top surface of the load-bearing frame 1. One side of the load-bearing frame 1 is connected to the segment vehicle 7 and moves synchronously with the segment vehicle 7.

[0037] Specifically, side baffles 3 are fixedly connected to the three sides of the top surface of the anti-slip panel 2. The side baffles are arranged around to form vertical edges. Specifically, 10 cm metal plates can be welded and connected. They can also be adjusted according to the actual materials and replaced with multiple blocks to complete the positioning of the items above when transporting.

[0038] The anti-slip panel 2 is welded or fastened to the load-bearing frame 1 by bolts, and is easy and quick to install. In one specific embodiment, the length of the platform after connection is 1300 mm and the width is 1100 mm.

[0039] Specifically, the anti-slip panel 2 is set to a single plate structure or a composite plate structure. When it is set to a single plate structure, a fish pattern plate is used. The thickness of the fish pattern plate is 5 mm, and the top surface of the fish pattern plate is provided with multiple protrusions, which effectively play an anti-slip function; when it is set to a composite plate structure, the bottom plate is selected from a flat metal plate, and a layer of rubber plate is connected to the top surface of the flat metal plate. The selection of the rubber plate realizes a flexible connection, which can better position the objects above and protect the surface of the flat metal plate.

[0040] The load-bearing frame 1 is formed by welding a plurality of steel sections together to form a square frame. The type and specification of the steel sections are not limited. The total width of the square frame after the connection can correspond to the segment vehicle.

[0041] Specifically, two or four bottom support beams 4 are provided at the bottom of the load-bearing frame 1, and the bottom support beams 4 are arranged symmetrically. The addition of bottom support beams can effectively improve the support force of the platform, prevent deformation of the top anti-slip panel, improve the overall strength and service life of the platform, and ensure the total weight of the items transported can be smoothly met.

[0042] like Figure 3 As shown, one side of the load-bearing frame 1 is welded to one side of the segment car 7, and a diagonal bracing beam 5 for reinforcement is provided between the bottom surface of the load-bearing frame 1 and the side wall of the segment car 7. The design of the diagonal bracing beam 5 improves the connection strength between the platform and the segment car. Specifically, the bottom support beam 4 and the diagonal bracing beam 5 can preferably be made of low-alloy light channel steel. A connecting ear 6 is connected to the other side of the load-bearing frame 1, and the connecting ear 6 is detachably connected to the next segment car 7 through a pin shaft. Specifically, the connecting ear is made of steel plate, designed in a U shape, and a connecting through hole is opened in the vertical direction.

[0043] The use process of this utility model is as follows:

[0044] Step 1: First, drive the vehicle vertically to the wellhead. After stopping at the wellhead, the gantry crane or mechanical crane arm will lift the material onto the platform. The operator only needs to stand on the ground and hold the material by hand. The material will fall stably on the non-slip panel 2 of the platform, reducing the frequency of high-altitude operations and lowering safety risks.

[0045] Step 2: During transportation, the speed of the train should not exceed 5 km / h to ensure safe transportation, and the materials should remain stable on the platform without shaking or sliding;

[0046] Step three: After the train is in place, stop the vehicle, lower the anti-slip hook, and install the iron shoe to limit the position; the operator unloads the materials.

[0047] Through the above three steps, the materials and segments can be placed separately during transportation, making the storage more stable and safe.

[0048] The shield segment transport vehicle platform is used in construction projects and can be used for eight trains in four tunnels in two sections. Each train can be equipped with a transport vehicle platform. The oil, bentonite and other materials required for shield construction can be placed on the platform, which effectively reduces the frequency of personnel climbing operations and reduces the pollution of oil to the segments. At the same time, it is safer during transportation, highly practical, and has good promotion value.
