Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and in particular to a double-head telescopic boom pump and a construction method of its cooperation with a secondary lining trolley. Background Art

[0002] The traditional secondary lining concrete pump is mainly composed of pump body, delivery pipeline, control system, etc. Among them, the pump body is the core part of the concrete pump, which pushes the concrete into the delivery pipeline through the rotating screw shaft. The delivery pipeline is responsible for transporting the concrete from the pump body to the inside of the tunnel. Different pipe lengths and diameters can be selected according to actual needs. The control system is responsible for controlling the rotation speed of the pump body and the switch of the delivery pipeline, so as to achieve precise control of concrete delivery.

[0003] Before using the traditional construction, the equipment should be fully inspected to ensure that all parts are intact and the delivery pipeline is not blocked. The ground pump needs to be connected to the delivery pipe of the secondary lining trolley; during use, the delivery speed and delivery volume of concrete should be strictly controlled to avoid construction quality problems caused by too fast or too slow delivery; during the delivery process, the condition of the delivery pipeline should be observed to promptly discover and deal with pipeline blockage and other problems. After use, the equipment should be cleaned and maintained to ensure long-term stable operation of the equipment.

[0004] In the traditional tunnel secondary lining concrete pouring, the concrete pump is also the main pouring equipment. This equipment cooperates with the secondary lining trolley to pour concrete, which is the traditional construction method for tunnel secondary lining pouring. This construction method is to convey concrete through pipelines by pressure. It is equipped with special pipelines, which can continuously transport concrete horizontally and vertically along the pipeline. It combines the production of ready-mixed concrete with pumping construction, and can realize the continuous pumping and pouring of concrete. The construction process of the secondary lining trolley pouring ground pump: the ground pump is manually pushed to the designated position, the ground pump port is connected with the pump pipe port of the secondary lining trolley, the equipment is started to pump concrete, the side window concrete is poured, the pipe vault concrete is poured, and the pipe is removed and the pipeline is cleaned after pouring.

[0005] However, with long-term use, limitations and disadvantages have also become apparent. For example, the ground pump is an unpowered structure and needs to be pushed forward each time. The ground pump is only a single concrete pumping mechanism. The pump pipe is installed on the secondary lining trolley in a crisscross pattern with a large degree of curvature, which can easily cause pipe blockage during the pouring process, affecting construction efficiency and secondary lining quality. Summary of the invention

[0006] In order to improve the problems of easy pipe blockage, low efficiency and long pouring time of ground pumps in traditional secondary lining construction, the present application provides a double-head telescopic boom pump and a construction method of its cooperation with a secondary lining trolley.

[0023] A method for cooperating a double-head telescopic boom pump with a secondary lining trolley is provided, based on the above-mentioned double-head telescopic boom pump, and comprises the following steps:

[0024] S1. The ground pump is installed on the power chassis to form the pumping system;

[0025] S2. Cancel the concrete pouring pump pipe on the second lining trolley and control the power chassis to move to a specified position;

[0026] S3. Control the folding cylinder so that the folding arm unfolds the main pump pipe until the two discharge ports of the double-headed pump pipe are aligned with the two casting windows on the corresponding sides of the second lining trolley;

[0027] S4.

[0034] 2. The boom pump used in this application transplants the main pump pipe and double-head pump pipe to the folding arm, eliminating the intricate pumping pipeline structure on the original secondary lining trolley, greatly reducing the risk of pipe blockage, reducing the time for manual takeover and the risk of pipe blockage, and also eliminating the pump pipe inspection process that must be performed before the traditional secondary lining trolley is poured, significantly improving construction efficiency. In traditional secondary lining pouring construction, each floor and each window needs to be connected to a pump pipe for concrete pouring. After using the boom pump of this application, only one main pump pipe and one double-head pump pipe are needed for 4 floors (8 windows per floor).

For example, only one person is needed to control the work of the folding arm to dock the pump pipe with the window position. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0042] The present application embodiment discloses a double-head telescopic boom pump. Figure 1 and Figure 2 , which includes:

[0043] The power chassis 1 is used for bearing and traveling. The power chassis 1 is specifically modified on the chassis of a truck and has four-wheel steering and driving functions.

[0044] The rotating support 11 is installed on the power chassis 1 and can realize 360° free rotation to be suitable for multi-directional angle adjustment.

[0045] The folding arm 4 is installed on the rotating support 11 and has multiple folding joints. The arm bodies on the folding arm 4 are connected through the folding joints. The folding arm 4 can be stably stored on the power chassis 1 after being fully folded. After being unfolded, the folding arm 4 can be folded at multiple angles with the help of the multiple folding joints, and can be conveniently pointed to a designated area in a narrow space in a tunnel. In this embodiment, the folding arm 4 is provided with four arm bodies.

[0046] The folding cylinder 9 is located at the folding joint of the folding arm 4 and is hinged to two adjacent arm bodies of the folding arm 4 . The folding cylinder 9 is used to adjust the angle between the two hinged arm bodies to achieve folding and unfolding control of the folding arm 4 .

[0047] The pumping system 2 is used for pumping concrete, which can be specifically a conventional ground pump installed on the power chassis 1; the aforementioned power chassis 1 is also provided with a power transfer case, which can transmit the power of the engine in the power chassis 1 to the rear axle or the ground pump, which can realize the walking function of the power chassis 1 and the normal operation of the ground pump, and can avoid the dependence of the conventional ground pump on external energy when working. In the specific setting, the power chassis 1 of the present application is a dual-power setting of engine and motor, the power of the engine provided thereon is used for walking and concrete pumping, and the power of the motor provided thereon is used for the operation of control components such as the folding cylinder 9 and the rotating support 11.

[0048] a main pump pipe 5 mounted on the folding arm 4 and connected to the output end of the pumping system 2; and

[0049] The double-headed pump pipe 6 is connected to the discharge end of the main pump pipe 5. The double-headed pump pipe 6 has two output pump pipes, which can be flipped on the main pump pipe 5 and the angle can be adjusted. At the same time, the double-headed pump pipe 6 is configured to be detachably connected to the main pump pipe 5, so that the output pump pipe can be replaced in time when blockage occurs, and rapid maintenance can be achieved, thereby reducing the impact on the progress of the secondary lining pouring construction.

[0050] After such arrangement, by installing the traditional ground pump on the power chassis 1, the mobility of the ground pump is increased, so that when pouring the second lining, the original manual pushing type is transformed into the driving type, which can reduce the labor intensity. Therefore, the arm pump of the present application can be quickly and flexibly moved to the construction site, and cooperate with the second lining trolley for rapid pouring, thereby improving the pouring efficiency.

[0051] Moreover, the boom pump of the present application transplants the main pump pipe 5 and the double-headed pump pipe 6 onto the folding arm 4, eliminating the complicated pumping pipeline transportation structure on the original secondary lining trolley, greatly reducing the risk of pipe blockage, reducing the time for manual unblocking due to pipe docking and pipe blockage, and also eliminating the pump pipe inspection process that must be performed before the traditional secondary lining trolley is poured, which has a positive effect on improving construction efficiency. At the same time, compared with the traditional secondary lining pouring construction, each floor and each window needs to be connected to a pump pipe for concrete pouring. After using the boom pump of the present application, only one main pump pipe 5 and one double-headed pump pipe 6 are needed for 4 floors (8 windows per floor), which not only greatly reduces the risk of concrete pipe blockage, but also can quickly replace the new pump pipe after the pipe is blocked, which does not affect the concrete pouring and can effectively ensure the efficiency of concrete pouring.

[0052] At the same time, with the help of the setting of the folding arm 4, not only can the storage of the main pump pipe 5 be facilitated, but also the pump pipe can be installed without manual docking. The folding arm 4 can be quickly and automatically unfolded with one button to deliver the pump pipe to each window, which greatly improves the efficiency of pump pipe layout, reduces the labor intensity of construction workers, and even reduces manpower. For example, only one person is needed to control the work of the folding arm 4 to dock the pump pipe with the window position.

[0053] In addition, refer to Figure 1 and Figure 2 A concrete receiving hopper 3 is provided on the power chassis 1, an input end of the pumping system 2 is connected to the concrete receiving hopper 3, and a concrete flow meter for measuring the volume of concrete is provided in the pumping system 2.

[0054] After such arrangement, when the second lining is poured, after the folding arm 4 controls the double-headed pump pipe 6 to align with the corresponding pouring window, the concrete pump truck first puts the concrete into the concrete receiving funnel 3, and then the pumping system 2 transports the concrete through the main pump pipe 5 to the two output pump pipes of the double-headed pump pipe 6 to pour the designated window; during the pouring process, the concrete flow meter can monitor the amount of pumped concrete, and by comparing the concrete volume monitored by the concrete flow meter with the designed concrete volume, possible abnormalities in the second lining pouring process can be analyzed and discovered in time, so that construction personnel can deal with construction abnormalities in time to avoid more serious consequences and economic losses.

[0055] Further, in order to expand the casting range of the boom pump of the present application, refer to Figure 1 and Figure 2The power chassis 1 is also provided with a telescopic arm 7 and a telescopic arm beam 8. One end of the telescopic arm 7 is connected to the part of the power chassis 1 close to the pumping system 2, and the other end is connected to the rotating support 11; the power chassis 1 is provided with a slide rail arranged along its travel direction, and the rotating support 11 is slidably arranged on the slide rail. With the arrangement of the telescopic arm 7, the telescopic arm 7 can push the rotating support 11 to slide on the power chassis 1, which can further improve the directional range of the output pump pipe on the double-headed pump pipe 6, so that there is no need to move the power chassis 1. Only with the telescopic arm 7 and the folding arm 4, all the pouring windows of the single pouring section of the second lining trolley can be poured, which greatly improves the pouring capacity of the arm pump of the present application; moreover, if the power chassis 1 is parked on the side of the second lining trolley, it will not affect the entry and exit of the slag removal vehicle and the simultaneous construction of the front excavation, and there is no need to move it frequently, which greatly improves the construction efficiency of the second lining pouring construction. For example, in the embodiment of the present application, by setting up the telescopic arm 7 and the folding arm 4, a construction length of 12 m can be achieved at one time, and the construction advantage is more obvious.

[0056] In addition, in order to ensure the stability of the boom pump of the present application during operation, refer to Figure 1 and Figure 2 Hydraulic legs 10 for supporting and balancing the power chassis 1 are installed at the four corners of the power chassis 1. By extending the four hydraulic legs 10, the power chassis 1 can be lifted to improve stability; and a control cab 12 is arranged on the rotating support 11, which can facilitate the operator to rotate along and observe the situation at the front end of the operation at any time.

[0057] The embodiment of the present application discloses a method for cooperating a double-head telescopic boom pump with a secondary lining trolley. Based on the above-mentioned double-head telescopic boom pump, referring to Figure 1 and Figure 3 , which comprises the following steps:

[0058] S1. The ground pump is installed on the power chassis 1 to form a pumping system 2, and the output end of the pumping system 2 is connected to the main pump pipe 5, wherein the power source of the ground pump can be provided by the engine on the power chassis 1;

[0059] S2. Cancel the concrete pouring pump pipe on the second lining trolley and control the power chassis 1 to move to the specified position;

[0060] S3. Control the folding cylinder 9 so that the folding arm 4 unfolds the main pump pipe 5 until the two discharge ports of the double-headed pump pipe 6 are aligned with the two casting windows on the corresponding sides of the second lining trolley;

[0061] S4. The concrete in the concrete pump truck is placed into the concrete receiving hopper 3 connected to the pumping system 2, and the pumping system 2 is started. The pumping system 2 delivers the concrete through the main pump pipe 5 to the double-headed pump pipe 6, so that the two pouring windows on both sides perform symmetrical pouring operations on both sides at the same time;

[0062] S5. After each layer of windows is cast, the folding cylinder 9 is controlled to transfer the double-head pump pipe 6 to the next layer of cast windows until the arch casting is completed.

[0063] Therefore, compared with the traditional second lining trolley casting construction: the ground pump needs to be pushed forward to the designated location manually, and its mobility is poor; before casting, it is necessary to check whether the pump pipes of each window are closed, and confirm which window is opened for casting, and the inspection operation is cumbersome; before casting, the pump pipe needs to be connected and installed with the ground pump interface, and the pump pipe needs to be replaced manually when casting the vault, which increases the manual pipe replacement time and reduces the casting efficiency; the pump pipes connecting the second lining trolley and the ground pump are complicated, which can easily cause concrete blockage. After the pipe is blocked, it is necessary to manually check the blockage location, and the long cleaning time leads to a series of problems such as concrete waste.

[0064] The construction method of the present application adopts a double-head telescopic boom pump and a secondary lining trolley for construction and pouring. The pump pipe + ground pump + power chassis 1 can be combined into one by installing a concrete delivery pump pipe on the folding arm 4 structure, which replaces the disadvantage that the traditional ground pump pouring still needs to install a pump pipe. The pouring position can be reached quickly, and the main pump pipe 5 and the double-head pump pipe 6 can be unfolded under the action of the folding arm 4 and the telescopic arm 7 to meet the double-head pouring on both sides of the 12-meter secondary lining trolley, which can significantly improve the construction efficiency and construction quality, and provide strong guarantee for tunnel construction.

[0065] Moreover, in terms of construction personnel configuration, when the traditional second lining trolley ground pump concrete is used for pouring construction, 6 construction personnel are required, including 2 people at the ground pump position, 2 people at the window position, and 2 people on the top of the trolley. The double-head telescopic boom pump of the present application is basically controlled by an automated program when it is used in conjunction with the second lining trolley. Only 2 people are needed to complete the pouring process, which greatly improves the safety of the operation and reduces the labor intensity of the personnel.

[0066] Among them, in step S4, the concrete pouring progress at the corresponding window is detected by means of the liquid level sensor set on the secondary lining trolley. When it is detected that the pouring amount of the window reaches the set value, the pumping system 2 is controlled to be closed. In this way, the pumping system 2 can be automatically closed at each set construction stage, without the need for personnel to be on duty at the high window, which not only improves the safety of the operation, but also ensures the construction quality.

[0067] Furthermore, in step S4, when pouring the windows on the same floor, a telescopic arm 7 is provided between the power chassis 1 and the rotating support 11, and the rotating support 11 is driven to slide on the power chassis 1 by the telescopic arm 7, so that the windows farther away can be poured without moving the power chassis 1. Thus, by means of the combination of the folding arm 4 and the telescopic arm 7, it can be ensured that each window of the 12-meter secondary lining trolley is poured normally without interference.

[0068] In addition, in step S2, the power chassis 1 is moved to the side of the designated position of the second lining trolley and kept in place so as not to interfere with the free passage of the slag truck.

[0069] The implementation principle of the coordinated construction method of a double-head telescopic boom pump and a secondary lining trolley in the embodiment of the present application is:

[0070] The boom pump used in this application transplants the main pump pipe 5 and the double-headed pump pipe 6 to the folding arm 4, eliminating the intricate pumping pipeline structure on the original secondary lining trolley, greatly reducing the risk of pipe blockage, reducing the time for manual takeover and the risk of pipe blockage, and also eliminating the pump pipe inspection process that must be performed before the traditional secondary lining trolley is poured, significantly improving construction efficiency. In the traditional secondary lining pouring construction, each floor and each window needs to be connected to a pump pipe for concrete pouring. After using the boom pump of this application, only one main pump pipe 5 and one double-headed pump pipe 6 are needed for 4 floors (8 windows per floor). After the pipe is blocked, a new pump pipe can be quickly replaced without affecting the concrete pouring, which can effectively ensure the efficiency of concrete pouring.

[0071] At the same time, with the help of the setting of the folding arm 4 and the telescopic arm 7, not only can the storage of the main pump pipe 5 be convenient, but also the pump pipe can be installed without manual docking. The folding arm 4 can be quickly and automatically unfolded with one button to deliver the pump pipe to each window, which can meet the double-head casting on both sides of the 12-meter second lining trolley, greatly improving the layout efficiency of the pump pipe, reducing the labor intensity of construction workers, and even reducing manpower. For example, only one person is needed to control the work of the folding arm 4 to dock the pump pipe with the window position.
