Technical Field

[0001] The utility model relates to the technical field of pouring construction safety, in particular to a terminal pipe structure for concrete pouring. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. It is widely used in various fields such as road engineering, bridge engineering, underground engineering, industrial and civil construction. In the construction of high-rise buildings, pumping equipment is required to pump concrete through a delivery pipe into the building for concrete pouring. The outlet of the pumping equipment delivery pipe is often equipped with an end pipe to guide the concrete pouring.

[0003] Due to the high-altitude operation, the terminal pipe will swing to a certain extent, so it is necessary to arrange an operator at the terminal pipe to assist in positioning and adjusting the terminal pipe. If the operator makes an operational error, steps on air, or the swing of the terminal pipe causes a fall accident, it is likely to cause personal injury to the operator, and the operator lacks safety protection.

[0004] To address this issue, the application document with application number 201210004596.3 discloses an end hose for pouring construction, on which a pouring construction safety device is installed. The pouring construction safety device includes at least one safety protection unit, and at least one safety protection unit is provided with a safety rope that can be tied to the operator and pulled to protect the operator in an emergency.

[0005] Although the above device can protect the life safety of the operator to a certain extent and prevent the occurrence of personal injury accidents, in actual application, the above device is still not sufficient to protect the life safety of the operator. Utility Model Content

[0009] Furthermore, there are two protection units, namely a first protection unit and a second protection unit.

[0010] Furthermore, the construction safety assurance device also includes a first pipe clamp, a second pipe clamp and a third pipe clamp; the first pipe clamp, the second pipe clamp and the third pipe clamp are respectively sleeved on the end pipe from top to bottom; the first assurance unit and the second assurance unit are symmetrically arranged on the first pipe clamp; the first pipe clamp and the second pipe clamp, and the second pipe clamp and the third pipe clamp are connected by a number of support rods.

[0011] Furthermore, the first pipe clamp, the second pipe clamp and the third pipe clamp have the same structure. The first pipe clamp includes a first clamping ring and a second clamping ring. The first clamping ring and the second clamping ring surround and are sleeved on the terminal pipe.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0027] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present application based on the specific circumstances.

[0028] For easier understanding, see Figure 1 The terminal pipe 1 in the embodiment of the present invention is a component connected to the end of the concrete pumping equipment. A construction safety device 2 is provided on the terminal pipe 1. The construction safety device 2 is sleeved on the terminal pipe 1 and includes a first pipe clamp 9, a second pipe clamp 10, and a third pipe clamp 11, which are sequentially provided on the terminal pipe 1 from the top downward, and a safety unit 3 provided on the first pipe clamp 9.

[0029] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the first pipe clamp 9, the second pipe clamp 10, and the third pipe clamp 11 have the same structure and all include a first clamp ring 12 and a second clamp ring 13. The first clamp ring 12 and the second clamp ring 13 are respectively fixed to the outer surface of the terminal pipe 1 at an appropriate height by a first bolt 14 and a second bolt 15. It should be noted that the first clamp ring 12 and the second clamp ring 13 have the same structure and are both semicircular. The first pipe clamp 9, the second pipe clamp 10, and the third pipe clamp 11 are equidistant and fixed to each other by a support rod 16. When an operator falls or is suspended in mid-air, the second pipe clamp 10 and the third pipe clamp 11 can serve as support points to share the operator's weight and the tension generated during the fall with the first pipe clamp 9. They are also used to ensure that the first pipe clamp 9 does not fall off the terminal pipe 1 in an emergency, thereby more fully protecting the operator's personal safety.

[0030] like Figure 1 and Figure 2As shown, the protection unit 3 is divided into a first protection unit 3a and a second protection unit 3b. The first protection unit 3a and the second protection unit 3b are symmetrically arranged on the first clamping ring 12 and the second clamping ring 13 of the first pipe clamp 9. The first protection unit 3a and the second protection unit 3b both include a shell 31, a rotating shaft 32 and a spiral spring 8; the shell 31 is also provided with a wire hole 33, which is located on the lower surface of the shell 31 for allowing the safety rope 4 to extend from the inside of the shell 31; the shell 31 is also provided with two fixing plates 7, and the two fixing plates 7 are provided with through holes for the rotating shaft 32 to pass through; the two ends of the rotating shaft 32 pass through the through holes on the two fixing plates 7 and are connected to the shell 31 bearing, so that The rotating shaft 32 can rotate inside the shell 31; a safety rope 4 is wound around the rotating shaft 32, and the safety rope 4 is located between the two fixed plates 7. One end of the safety rope 4 is connected to the rotating shaft 32, and the other end is provided with a safety buckle 19. The safety rope 4 can be connected to the safety belt worn by the operator through the safety buckle 19 to ensure the personal safety of the operator; an emergency locking mechanism 5 and a volute spring 8 are respectively provided on the two fixed plates 7. The emergency locking mechanism 5 is used to brake the rotating shaft 32 so that the rotating shaft 32 stops rotating, thereby controlling the length of the safety rope 4 extending out of the pull wire hole 33, and the volute spring 8 is used to drive the rotating shaft 32 to rotate so that the safety rope 4 wrapped around the rotating shaft 32 is reset from the stretched state.

[0031] like Figure 3 As shown, the emergency locking mechanism 5 includes a brake disc 51 and a rotating disc 52; the brake disc 51 is disc-shaped, with a hollow center, and a plurality of recessed openings are provided on the inner ring of the brake disc 51, so that the brake disc 51 can engage with the rotating disc 52; the rotating disc 52 is fixedly sleeved on the rotating shaft 32 and is located inside the brake disc 51. A fixed seat 20 and a plurality of movable teeth 521 are provided on the surface of the rotating disc 52. One end of the movable tooth 521 is hinged to the rotating disc 52, so that the movable tooth 521 can perform circular motion with the hinge position as the axis; the other end of the movable tooth 521 can engage with the opening on the brake disc 51, and is connected to the fixed seat 20 on the rotating disc 52 through a coil spring 6, so that the circular motion of the movable tooth 521 with the hinge position as the axis is constrained.

[0032] When the operator slips and falls, the safety rope 4 connected to the operator's safety belt quickly extends from the housing 31, driving the rotating shaft 32 to rotate rapidly to generate inertial centrifugal force, causing the movable tooth 521 to move outward with the hinge position as the axis until the other end of the movable tooth 521 engages with the opening on the brake disc 51. The emergency locking mechanism 5 is in a locked state, the rotating shaft 32 stops rotating, and the operator connected to the safety rope 4 no longer falls, fully ensuring the personal safety of the operator.

[0033] like Figure 4As shown, one end of the vortex spring 8 is fixedly connected to the rotating shaft 32, and the other end is connected to the fixed plate 7 through the fixing seat 20. It should be noted that when the safety rope 4 is stretched by the operator, the rotating shaft 32 is driven to rotate, and the vortex spring 8 is gradually tightened. When the operator releases the connection with the safety rope 4, the vortex spring 8 will drive the rotating shaft 32 to rotate in the opposite direction, thereby driving the safety rope 4 to automatically reset, which is convenient and quick, and there is no need for the operator to retract the safety rope 4.

[0034] like Figure 5 and Figure 6 As shown, the second pipe clamp 10 and the third pipe clamp 11 are both provided with a first lifting ring 17 for the safety rope 4 to pass through, so as to restrict the range of movement of the safety rope 4 to prevent the safety rope 4 from getting entangled and affecting the personal safety of the operator; the third pipe clamp 11 is also provided with a second lifting ring 18 for the safety rope 4 to be connected through a safety buckle 19 (the safety buckle 19 is buckled on the second lifting ring 18), which is convenient for the operator to take. It should be noted that the safety rope 4 passes through the pull wire hole 33, the first lifting ring 17 and the second lifting ring 18 in sequence from top to bottom and is connected through the safety buckle 19. Since the protection unit 3 is provided on the first pipe clamp 9, when the first pipe clamp 9 is provided at a higher position of the terminal pipe 1, the operator can directly take the safety buckle 19 from the second lifting ring 18 of the third pipe clamp 11 and connect it to the safety belt worn by himself.

[0035] Optionally, one end of the first clamping ring 12 and the second clamping ring 13 may be connected in a hinged manner, and the other end may be connected by bolts.

[0036] Optionally, the construction safety assurance device 2 can be integrated with the terminal pipeline 1 without the need for bolt connection.

Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
