Description

Technical field

The invention relates to the technical field of tunnel construction, and in particular to a longitudinal movement pump tube mechanism, a distribution system and a distribution method including the longitudinal movement pump tube mechanism.

Background technique

At present, tunnel construction has developed from concrete pouring with lapped wooden formwork to the use of automatic pouring trolleys (hereinafter referred to as trolleys) for concrete pouring. The automatic pouring trolley also uses pumping to pour concrete. The concrete is pumped to the top of the trolley through a distribution trolley. The distribution trolley moves longitudinally and connects to the distribution pipeline to pour the pumped concrete to the top of the trolley or to the top of the trolley. bottom.

The distribution system on the pouring trolley uses a large number of pipelines for concrete pouring. Almost every pouring port has a separate set of pipelines (from the pouring port to the interface of the placing machine) for control. Take a 12m trolley as an example. Generally, 8 to 16 sets of pipelines are used.

The existing distribution system has the following defects: ① In this distribution system, except for the material at the top of the top mold, which is fed through the pouring port, the rest of the materials are mostly fed through the working window. Compared with the feeding method of the pouring port, the working window To feed materials, you need to open the working window first and then connect a section of the feeding pipe. This not only increases the labor intensity of workers, reduces work efficiency, but also increases the maintenance cost of the pipeline, which is not conducive to the automation and mechanization of trolley pouring; ② A large number of pipelines not only increases the weight and cost of the trolley, but also places high requirements on the maintenance and cleaning of the pipelines, and is even prone to pipe blockage; ③ The application of a large number of pipelines will also produce a large number of joints , the joint docking takes a lot of time, which seriously affects the pouring efficiency during concrete pouring.

Detailed ways

The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

Example:

A longitudinally moving pump tube mechanism, including a support frame 1, a walking assembly 2 and a pump tube group 3, as shown in Figures 1-3, details are as follows;

The support frame 1 includes a connected first frame body 1.1 and a second frame body 1.2. The first frame body 1.1 and the second frame body 1.2 are preferably designed in an L-shaped structure. The first frame body 1.1 and the second frame body 1.2 are preferably 1.2 are all set on the truss piece 4 on the mast.

The pump tube set 3 includes at least one pump tube 3.1 (Figure 1-2 illustrates one tube, which can be set into a Y-shaped tube according to actual needs). The first end of the pump tube 3.1 is arranged on the first frame body. 1.1, and the first end is provided with a first pump tube interface 3.2 (preferably the first pump tube interface is arranged at the end); the second end of the pump tube 3.1 is movably arranged on the second frame 1.2 to realize the pump The distance between the first end and the second end of the tube is adjusted, and the second end is provided with a second pump tube interface 3.3 (preferably the second pump tube interface is provided at the end).

Preferably here: between the first pump pipe interface and the butt piece A (here the conveying pipe on the distributor or the connecting pipe connected to the distributor) and/or between the second pump pipe interface and the butt piece B (here the pouring machine) or pouring pipes); here it is preferred that both the first pump pipe interface 3.2 and the second pump pipe interface 3.3 adopt U-shaped rubber joints, which has two effects: on the one hand, the use of flexible butt joints can prevent The reserved pouring port of the formwork may be damaged due to operating errors; on the other hand, the rubber joint also acts as a sealing gasket to ensure the pressure in the pouring pipe, prevent air leakage and pressure release, and realize the pressure-maintaining feeding of the longitudinally shifting pump pipe mechanism, both It can improve the pouring efficiency and expand the choice of installation location of the distributor, which is highly practical.

Here, it is preferred that the pump tube and the first pump tube interface and/or the pump tube and the second pump tube interface are connected by a pipe clamp. Generally speaking, the pouring of the top mold usually uses a straight pipe to connect the reserved pouring opening on the top mold, while the pouring of the side mold needs to be replaced by a 45° joint pouring. The connection method of pipe clamps can ensure the convenience of interchange of straight pipe joints and elbow joints on the one hand, and on the other hand it can improve the convenience of replacing parts (such as the first pump pipe interface, the second pump pipe interface or the pump pipe). sex.

The walking assembly 2 is arranged on the support frame and is used to drive the entire longitudinal movement pump tube mechanism to move. It is preferred here that the walking assembly 2 includes a driving member 2.1 and a traveling wheel set 2.2 connected to the driving member 2.1. The driving member is arranged on (preferably below) the second frame 1.2 in the support frame, and the driving member is a walking wheel set 2.2. The movement of the wheels provides the power. Further preferably: the running wheel set includes a set of A running wheels 2.21 and a set of B running wheels 2.22, the set of A running wheels are arranged on the first frame and the rotation axis of the A set of running wheels is arranged along the vertical direction; so The B group of traveling wheels is arranged on the second frame body and the rotation axis of the B group of traveling wheels is arranged in the horizontal direction. The trolley connected to the longitudinal shift pump tube mechanism is equipped with an upper track 5 and a lower track 6, see Figure 2-Figure 3. The upper track matches the A group of traveling wheels 2.21, the lower track matches the B group of traveling wheels 2.22, and the upper track matches the A group of traveling wheels 2.21. Channel steel is used to fix the running wheel mechanism. The lower track is made of channel steel but is deflected 90° to fix the running wheel mechanism. The inner side is welded to the square tube to limit the position. The advantage of this design is to make full use of the weight of the mechanism itself to ensure that the walking components are not It will derail. Due to the structure of the cantilever beam, the center of the entire mechanism falls near the driving part, and the lower rail is equivalent to the fulcrum of the entire longitudinal shift pump tube mechanism. The upper rail 5 plays a limiting role, using its own gravity to ensure that Group A The contact between the running wheel 2.21 and the upper track.

Preferably in this embodiment, the lower rail 6 is provided with a rack 7 with the tooth surface of the rack facing downward; the driving member is provided with a gear matching the rack.

Preferably in this embodiment, the second frame body 1.2 includes a fixed section 1.21 and a movable section 1.22.

It is preferable that the telescopic member is an oil cylinder or a pneumatic cylinder. Further preferably, the second end of the pump tube and/or the second pump tube interface are movably arranged on the movable section through the clamping member 1.3. The design of the clamping piece can ensure that the second pump tube interface 3.3 can automatically adjust the angle (fine adjustment) when docking with the docking piece B, further ensuring the airtightness of the pipeline during docking. It is preferable that the clamping member 1.3 adopts a combined design of a C-shaped bending plate and a connecting column. The C-shaped bending plate is detachably connected to the second end of the pump tube and/or the second pump tube interface, and the connecting column is arranged in the movable section. On the C-shaped bending plate and the second pump tube interface, the C-shaped bending plate and the second pump tube interface can be swung at a certain angle in the vertical plane around the axis of the connecting column, thereby achieving fine adjustment when the second pump tube interface is docked and meeting the alignment requirements.

In this embodiment, a limiting device is also provided to prevent the traveling assembly from derailing, and the limiting device is provided on the second frame body and/or the track. It can effectively prevent derailment when the longitudinal shift pump tube mechanism is connected with other components (such as the distribution trolley).

The longitudinal movement pump tube mechanism of this embodiment is applied to a distribution system. The distribution system specifically includes a docking member B and the longitudinal movement pump tube mechanism as described above. The distribution system is used in combination with a trolley. The mast of the trolley is provided with a The tunnel has tracks in the same length direction; the docking piece B includes at least two sets of docking single pieces arranged along the length direction of the tunnel; the longitudinal shift pump tube mechanism is movably installed on the gantry of the trolley, and the longitudinal shift pump tube mechanism The traveling assembly in the longitudinal movement pump tube mechanism matches the track; the second end of the pump tube in the longitudinal movement pump tube mechanism is connected to the docking single piece through the second pump tube interface. The specifics here are:

For the top formwork: The butt piece B here is the pouring port. The distributor is connected to the longitudinal movement pump tube mechanism, and the longitudinal movement pump tube mechanism directly transports concrete to the pouring port. When the position of the placing machine is higher than the pouring port, the longitudinal shift pump pipe mechanism plays the role of connecting the pipeline, directly connecting the placing machine and the pouring port. The concrete enters the pouring port under the action of gravity (traditional injection relies on pure gravity, The concrete height cannot be higher than the lowest level of the pouring opening). When the installation position of the distributor is low (for example, the outlet of the distributor is lower than the pouring opening), the longitudinal shift pump tube mechanism can play the dual functions of maintaining pressure and connecting. Under the action of pressure, the concrete can enter smoothly. Distribution is realized in the pouring port, and the height of the injected concrete can be higher than the lowest level of the pouring port or even higher than the highest level of the pouring port. Injection under pressure improves the density and quality of concrete. For the side formwork: The butt piece B here is a pouring pipe (such as a chute, etc.), the distributor is connected to the longitudinal pump pipe mechanism, and the longitudinal pump pipe mechanism is connected to the pouring pipe to realize the transportation of concrete. Based on the longitudinal shift pump tube mechanism, it can be designed into two structures: connected or pressure-maintaining and connected. The installation position of the distributor is the same as the top template (flexible and changeable).

Therefore, the distribution system of this embodiment adopts the design of the longitudinally shifting pump tube mechanism, which can not only simplify the pipeline of the distribution system, but also ensure that the installation position of the distribution machine is flexible and highly practical.

In this embodiment: the channel steel can be made wider at the track, and the driving parts can be placed in it, so that the driving parts can also be responsible for the role of the running wheels; the floating mechanism design of the running wheel set can also be set on the track, and set at the rack end. Floating device (preferred here: the connection between the gear and the rack is a floating connection, and the preload force is provided by the spring to ensure effective contact between the gear and the rack, and can also protect the traveling assembly under working conditions after the rack is contaminated by concrete), Floating device that replaces the drive mechanism.

Applying the cloth distribution system of this embodiment to cloth includes the following steps:

Fabric construction, including:

Step ②: Extend the second end of the pump tube to the corresponding position so that the second pump tube interface is connected to the docking single piece for cloth distribution;

In this embodiment, when the longitudinal movement pump tube mechanism moves longitudinally, the telescopic member must be shortened accordingly to prevent interference (such as collision, etc.) between the longitudinal movement pump tube mechanism and other components (such as vertical supports, etc.).

Applying the solution of this embodiment, a new pouring system can be formed by a distributing trolley and longitudinally shifting pump tube mechanisms distributed on both sides of it. The effects are: ① The longitudinally shifted pump tube mechanism can slide longitudinally along the trolley and adopts modularization The design greatly reduces the use of pump pipes (the longitudinal shift pump pipe mechanism can replace a large number of pouring pipes located in the top mold and other parts of the trolley in the original distribution system, simplifying the structure, and also Pouring becomes standardized and modular); ② The pouring pipeline is simplified and the working space inside the trolley is increased; the reduction of pipelines also greatly reduces the risk of pipe blockage and reduces the cost of pipe replacement; ③ The flexible connection between the longitudinally moving pump tube mechanism and the pouring pipe or the placing machine can realize pouring under pressure and provide concrete density. The installation position of the placing machine can be flexibly selected, making it highly practical.

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
