Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring in building engineering construction, in particular to a flow-stopping device for a material discharging port of a concrete placing machine. Background Art

[0002] Concrete is one of the most important building materials in contemporary times. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. Concrete placing boom is a commonly used equipment for pouring concrete. The working principle of concrete placing boom is mainly to deliver the concrete delivered by pump pressure to the formwork of the component to be poured through the pump pipe. Specifically, the front end of the feed elbow of the concrete placing boom is connected to the end of the concrete pump pipe to form a complete pumping output pipeline. Under the working pressure of the ground pump, the concrete in the hopper is continuously transported to the target component formwork range through the concrete delivery pipeline and the rotation of the main beam frame and the second section pipe. The use of concrete placing boom can greatly improve the efficiency and quality of concrete pouring, reduce the intensity of manual labor, and provide a more uniform and continuous pouring effect, thereby improving the construction speed and the density of the concrete structure.

[0003] A concrete placing boom is the terminal equipment for pumping concrete. Its function is to deliver the pumped concrete through a pipe to the formwork of the component to be cast. During the concrete pouring process, existing concrete placing booms often have the problem of difficult-to-control concrete outflow, which leads to spillage everywhere, causing material waste and reduced construction efficiency. Especially when the concrete placing boom is used to pour concrete of different grades for slabs and columns separately, the delivery of concrete by the ground pump needs to be suspended each time the pouring point is switched. However, even if the existing concrete placing boom suspends the delivery of concrete by the ground pump, the concrete in the pump pipe will spill outside the target component. If the time interval between the pouring of different components is long, the spilled concrete will form cold joints, which will cause a series of engineering quality problems, and the on-site aesthetics during the concrete pouring process will be extremely poor. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a flow-stop device at the discharge port of a concrete placing boom, which is used to solve the problem of concrete spilling everywhere during the movement of the discharge port of the concrete placing boom after the pump is stopped. It can avoid the phenomenon of concrete spilling everywhere in the pump pipe during the movement of the discharge port of the concrete placing boom after the pump is stopped, reduce waste during the pouring process, and reduce the loss of some building materials.

[0005] To achieve the above-mentioned purpose, the utility model provides a flow-stop device for a material distribution machine outlet, comprising an iron sheet wrapped around the end of a hose at the material distribution machine outlet, a pump pipe, and a clamp assembly connected between the iron sheet and the pump pipe; the clamp assembly comprises two hingedly connected semicircular clamps, and the non-hinged ends of the two semicircular clamps are both provided with double-ear seats, one of the double-ear seats is plugged with a fixing bolt from top to bottom, and a horizontally arranged adjusting bolt is sleeved on the fixing bolt, and the adjusting bolt extends into the other double-ear seat and is tightened with a nut to close and fix the two semicircular clamps; the pump pipe is provided with a concrete flow-stop valve for blocking the concrete in the pipe from leaking outward.

[0006] Optionally, the concrete stop valve comprises a metal baffle rotatably connected to the pump pipe, and the metal baffle passes through a groove cut on the pump pipe to seal the through hole of the pump pipe.

[0007] As above, a metal baffle is connected to the groove cut on the pump pipe to form a concrete stop valve with the groove on the pump pipe, so as to block the concrete in the pipeline after the ground pump stops delivering.

[0008] Furthermore, the metal baffle includes a baffle round cover for blocking the through hole of the pump tube and a baffle handle for rotating the baffle round cover.

[0009] Optionally, the outer peripheral surfaces of the iron sheet and the pump pipe connected to the clamp assembly are both provided with threaded openings.

[0010] From the above, the iron sheet wrapped at the end of the hose at the feed placing machine's discharge port is to make the end of the hose at the feed placing machine's discharge port more wear-resistant and easy to operate. The end of the hose at the feed placing machine's discharge port is wrapped with iron sheet, and it is ensured that the iron sheet after wrapping has a threaded mouth, which is convenient for the end to be connected to the pump pipe and to be firmly connected to the pump pipe through a clamp.

[0011] Furthermore, a leather ring is arranged inside the clamp assembly.

[0012] Optionally, the wrapping length of the iron sheet is 20 cm, and the length of the pump tube is 30 cm.

[0013] Furthermore, the thickness of the metal baffle is adapted to the thickness of the groove.

[0014] From the above, compared with the prior art, the flow-stopping device for the material placing machine outlet of the utility model has at least the following beneficial effects:

[0015] 1. The utility model adds a section of pump pipe to the material discharging port of the concrete placing machine, and sets a valve for controlling the flow of concrete in the added pump pipe. This device has strong operability and no obvious defects, and can accurately control the delivery of concrete, reducing waste in the pouring process;

[0016] 2. It is suitable for a variety of construction environments, improving the versatility and practicality of the concrete placing machine;

[0017] 3. When pouring concrete of different strength grades for different components, it can prevent concrete from spilling into non-target components, thereby preventing some engineering quality problems.

[0018] 4. When the local pump is delivering concrete to the concrete placing machine for pouring, the stop valve of the discharge port can be opened, and when the local pump stops delivering concrete, the valve can be closed to avoid spilling of concrete. The utility model solves the technical problem that concrete in the pump pipe still spills from the discharge port of the concrete placing machine when the pump is stopped.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See below Figure 1 to Figure 3 The flow stopping device at the material distributing machine outlet of the utility model is described in detail.

[0027] like Figure 1-3 As shown, the flow-stop device for the material placing machine outlet of the utility model comprises an iron sheet 2 wrapped around the end of a hose 1 of the material placing machine outlet, a section of a pump pipe 4 with a groove 14 cut therein, and a clamp assembly 3 connected between the iron sheet 2 and the pump pipe 4.

[0028] The end of the hose 1 of the feed distributing machine outlet is wrapped with iron sheet 2 to increase practicality and wear resistance. This is also the setting method of the commonly used feed distributing machine outlet. Usually, the wrapping length of the iron sheet 2 at the end of the hose 1 of the feed distributing machine outlet is 20 cm, and a threaded opening is set on the outer peripheral surface of the iron sheet 2, which is convenient for connecting the pump pipe 4 with the clamp assembly 3. The pump pipe 4 and the hose 1 of the feed distributing machine outlet are connected by the clamp assembly 3 by wrapping the iron sheet 2 and setting the threaded opening. The threaded opening on the iron sheet 2 is connected to the pump pipe threaded opening 13 on the outer peripheral surface of the pump pipe 4 through the clamp assembly 3. The clamp assembly 3 ensures firmness by connecting the threaded opening on the iron sheet 2 and the pump pipe threaded opening 13 on the pump pipe 4, and a leather ring 7 is usually set inside the clamp assembly 3 to ensure the sealing of the overall connection.

[0029] like Figure 2 As shown, the function of the clamp assembly 3 is to connect the iron sheet 2 and the pump pipe 4 wrapped at the end of the hose 1 of the material placing machine outlet. The clamp assembly 3 includes two hinged semicircular clamps 9 and 10. The non-hinged ends of the two semicircular clamps 9 and 10 are both provided with double-ear seats. A fixing bolt 8 is inserted from top to bottom on one of the double-ear seats. A horizontally arranged adjusting bolt 6 is sleeved on the fixing bolt 8. The adjusting bolt 6 extends into the other double-ear seat and is tightened with a nut to close and fix the two semicircular clamps. The purpose of the fixing bolt 8 is to connect the adjusting bolt 6. The two semicircular clamps 9 and 10 are connected by the adjusting bolt 6, so that the two semicircular clamps 9 and 10 can be closed, fixed or opened. The adjusting bolt 6 facilitates the connection and disconnection of the two semicircular clamps 9 and 10, and is convenient for the installation and removal of the clamp assembly 3. The clamp assembly 3 adopts the form of assembling two semicircular clamps 9 and 10 to make the connection more practical and convenient.

[0030] like Figure 3As shown, a concrete stop valve is provided in the pump pipe 4 to block the concrete in the pipe from leaking out. The concrete stop valve includes a metal baffle 5 rotatably connected to the pump pipe 4, and the metal baffle 5 passes through the groove 14 cut on the pump pipe 4 to block the through hole of the pump pipe 4. The metal baffle 5 includes a baffle round cover 12 for blocking the through hole of the pump pipe 4 and a baffle handle 15 for rotating the baffle round cover 12. The metal baffle 5 arranged at the position of the groove 14 is to form a concrete stop valve with the groove 14 cut on the pump pipe 4, which plays a role in blocking the concrete in the pipe from leaking out. The metal baffle 5 is rotatably connected to the connecting seat outside the pump pipe 4 by bolts 11. The thickness of the metal baffle 5 is close to the height of the groove 14. The baffle handle 15 facilitates the rapid closing and opening of the concrete stop valve.

[0031] The baffle round cover 12 is close to the through hole size of the pump pipe 4, and a baffle handle 15 of about 10 cm is provided on the baffle round cover 12 for easy operation. When the concrete stop valve is closed, the concrete flowing in the pipeline exerts an extrusion force on the metal baffle 5 so that the baffle round cover 12 will not be easily opened, so that the concrete will not be spilled. When opening, the pump pipe 4 can be placed horizontally to open it easily.

[0032] The concrete placing machine discharge port hose 1 is a structure commonly used for concrete placing machine discharge port settings. The concrete placing machine discharge port hose 1 is more convenient when pouring concrete and makes concrete discharge smoother. The iron sheet 2 wrapped at the end of the concrete placing machine discharge port hose 1 is to increase the practicality and wear resistance of the concrete placing machine discharge port hose 1. The clamp assembly 3 is used to connect and fix the iron sheet 2 and a section of pump pipe 4 cut with a groove 14. The end of the concrete placing machine discharge port hose 1 is connected with a section of pump pipe 4 in order to set a metal baffle 5 at the position corresponding to the groove 14, so that the groove 14 on the pump pipe 4 and the metal baffle 5 form a concrete stop valve.

[0033] Since it is not convenient to set a stop valve on the discharge hose 1 of the concrete placing machine, it is considered to connect a section of pump pipe 4 and set a concrete stop valve on the pump pipe 4. The purpose of connecting a section of pump pipe 4 is to set a concrete stop valve in the pump pipe 4. In order to consider the convenience of moving the discharge port of the concrete placing machine in reality, the length of the pump pipe 4 can be set to 30 cm.

[0034] Optionally, the groove 14 cut in the pump tube 4 is set in the middle position, and the height of the groove 14 is set at about 1 cm.

[0035] The flow stop device for the concrete placing machine outlet of the utility model can prevent the concrete in the pump pipe from spilling out of the concrete placing machine outlet when the local pump stops delivering concrete, that is, the device plays the role of a concrete flow stop valve to block the concrete in the pump pipe when the pump stops. The device is simple and practical, and has no obvious defects or loopholes, which can provide certain convenience for the concrete placing machine to pour concrete.

[0036] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
