Description

Technical Field

[0001] The invention relates to the field of concrete pouring funnels, in particular to a telescopic concrete pouring funnel. Background Art

[0002] With the gradual development of power grid construction, there are more and more cable trenches with different voltage levels such as 110kV and 220kV, and the number of up-down projects is also increasing. Due to the different voltage levels and different design requirements of cable trenches, the wall thickness of cable trenches varies from 120mm to 800mm. And the thinner the side wall of the cable trench, the more difficult it is to pour concrete, which also makes it difficult for traditional concrete pouring funnels to meet current engineering needs. In the actual construction process, construction units generally use self-made chutes or traditional concrete pouring funnels, the bottom of which is a circular discharge port with fixed size. As a result, during the construction of the side wall of the cable trench, due to the large size of the discharge port, concrete is easily spilled into the cable trench to form hard concrete blocks. Make the bottom plate of the cable trench uneven. And during the cable laying process, it is very easy to scratch the outer sheath of the cable, causing damage to the cable body and affecting the use of the cable. Summary of the invention

Through the control of the telescopic device, the left funnel wall plate and the right funnel wall plate can move closer to each other or away from each other, which makes the size of the funnel adjustable according to different casting width requirements. It can achieve precise adaptation for the side walls of cable trenches of different widths, thus improving the flexibility and adaptability of construction. Concrete will not spill into the cable trench to form hard concrete blocks due to the large size of the discharge port, preventing the bottom plate of the cable trench from becoming uneven due to the spilled concrete blocks, thereby avoiding damage to the laid cables.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-4As shown, a telescopic concrete pouring funnel includes a left funnel wall panel 1, a right funnel wall panel 2, a front connecting baffle 3 and a rear connecting baffle 4, the front connecting baffle 3 is connected between the front ends of the left funnel wall panel 1 and the right funnel wall panel 2, and the rear connecting baffle 4 is connected between the rear ends of the left funnel wall panel 1 and the right funnel wall panel 2, so that the left funnel wall panel 1, the right funnel wall panel 2, the front connecting baffle 3 and the rear connecting baffle 4 are surrounded by a funnel shape, and the lower end of the funnel is a discharge port, and the left funnel wall panel 1 and the right funnel wall panel 2 are connected with a telescopic device that can make the left funnel wall panel 1 and the right funnel wall panel 2 move closer to each other or away from each other, and the front connecting baffle 3 and the rear connecting baffle 4 can be passively folded or unfolded to the left and right under force when the telescopic device is extended and retracted.

[0022] In order to change the width of the discharge port at the lower end of the funnel, the left funnel wall plate 1 includes a left funnel plate portion 101 and a left fixed plate portion 102 located above the left funnel plate portion 101, and the right funnel wall plate 2 includes a right funnel plate portion 201 and a right fixed plate portion 202 located above the right funnel plate portion 201. The telescopic device includes four telescopic rods 5 symmetrically arranged on the front and rear sides of the funnel, and two are arranged in an up-and-down arrangement on the front and rear sides. The left and right ends of the telescopic rods 5 are respectively connected and fixed to the left fixed plate portion 102 and the right fixed plate portion 202. The telescopic movement of the telescopic rods 5 drives the relative movement of the left fixed plate portion 102 and the right fixed plate portion 202, and then drives the relative movement of the left funnel plate portion 101 and the right funnel plate portion 201, so as to change the width of the discharge port at the lower end to adapt to the side walls of the cable well trench of different widths. By arranging the telescopic rods 5 on the front and rear sides of the funnel, the influence of concrete falling from top to bottom on the telescopic rods 5 can be reduced.

[0023] For the convenience of subsequent maintenance, the left and right ends of the telescopic rod 5 are connected and fixed to the left fixed plate portion 102 and the right fixed plate portion 202 by fixing bolts 6. Connected by fixing bolts 6, connection, fixing and disassembly are all convenient, which is convenient for subsequent replacement and maintenance.

[0024] In order to realize the telescopic and temporary fixing structure of the telescopic rod 5, the telescopic rod 5 includes a rod sleeve 501 and a rod body 502. The rod body 502 can be movably inserted into the rod sleeve 501. The rod sleeve 501 is provided with clamping holes arranged along the axial direction. The rod body 502 is provided with elastically supported clamping beads at positions corresponding to the clamping holes. When the rod body 502 and the rod sleeve 501 are moved until the clamping beads are embedded in the clamping holes, the rod body 502 and the rod sleeve 501 are temporarily fixed. The telescopic and temporary fixing structure is simple, and the telescopic and temporary fixing structure of the telescopic rod 5 is effectively realized.

[0025] In order to realize the connection between the front connecting baffle plate 3 and the rear connecting baffle plate 4, the front and rear ends of the left funnel wall plate 1 and the right funnel wall plate 2 are provided with a clamping groove 7, and the left and right ends of the front connecting baffle plate 3 and the rear connecting baffle plate 4 are connected through the clamping groove 7. The height of the front connecting baffle plate 3 and the rear connecting baffle plate 4 is the same as the height of the left funnel plate portion 101 and the right funnel plate portion 201. Through the clamping of the clamping groove 7, the connection and fixing are convenient.

[0026] In order to prevent concrete from falling out of the template, a left discharge port baffle portion 103 is provided at the lower end of the left funnel wall plate 1, and a right discharge port baffle portion 203 is provided at the lower end of the right funnel wall plate 2. The left discharge port baffle portion 103 and the right discharge port baffle portion 203 are parallel to each other. The parallel discharge port baffles make the discharge port rectangular. After adjusting the width by the telescopic rod 5, the left and right discharge port baffle portions are located in the template of the side wall of the cable well trench to be poured, so as to prevent concrete from falling out of the template.

[0027] In order to facilitate the mobile continuous construction on the template of the long cable trench side wall, three pulleys 8 are symmetrically arranged on the left side of the left discharge port baffle part 103 and the right side of the right discharge port baffle part 203. The pulleys 8 are arranged at equal intervals, and the axial direction of the pulleys 8 is left and right. The pulleys 8 are supported on the template outside the discharge port baffle part, which facilitates the mobile continuous construction on the template of the long cable trench side wall, thereby improving the convenience and speed of construction.

[0028] In order to realize the firm structure of the left funnel wall plate 1 and the right funnel wall plate 2, the parts of the left funnel wall plate 1 and the right funnel wall plate 2 are welded by plate materials, so that the integrity is strong and the structure is firm and reliable.

[0029] In order to realize the overall reduction of the width of the discharge port, the slot 7 is a slot hole that penetrates in the left and right directions, and the front connecting baffle plate 3 and the rear connecting baffle plate 4 can move in the left and right directions in the slot 7. When the left funnel wall plate and the right funnel wall plate move relatively, the front connecting baffle plate 3 and the slot 7, and the rear connecting baffle plate 4 and the slot 7 also slide accordingly, adapting to the relative movement of the left funnel wall plate 1 and the right funnel wall plate 2, and realizing the overall reduction of the width of the discharge port.

[0030] In order to realize the expansion or folding of the front connecting baffle 3 and the rear connecting baffle 4, the front connecting baffle 3 and the rear connecting baffle 4 are both formed by a plurality of vertical plates hinged to each other in the left and right directions. The hinged structure facilitates the rotation of the connection, can effectively realize the folding or expansion of the front connecting baffle 3 and the rear connecting baffle 4, can realize a wider funnel for the wider side wall of the cable well trench, and better adapt to the relative movement of the left funnel wall plate 1 and the right funnel wall plate 2.

[0031] When in use, adjust the length of the telescopic rod 5, move the rod body 502 of the telescopic rod 5 in the rod sleeve 501, and use the elastically supported card bead to cooperate with the card hole to temporarily fix the telescopic rod 5 in the desired position, so that the distance between the two outer sides of the left discharge port baffle part 103 and the right discharge port baffle part 203 is smaller than the inner side spacing of the template of the cable well trench side wall to be poured, and place the funnel above the template of the cable well trench side wall to be poured, ensuring that the left discharge port baffle part 103 and the right discharge port baffle part 203 are located on the inner side of the template to prevent concrete from flowing out of the template during construction. The pulley 8 is located at the upper end of the template on both sides of the cable well trench side wall, and then concrete pouring can be carried out. When the cable well trench side wall is long and continuous construction is required, the pulley 8 is used to move on the template to achieve continuous and efficient pouring operations.

[0032] By operating the telescopic rod 5, the left funnel wall panel 1 and the right funnel wall panel 2 can be moved closer to each other or away from each other, which makes the size of the funnel adjustable according to different casting width requirements. It can achieve precise adaptation for the side walls of cable trenches of different widths, thereby improving the flexibility and adaptability of construction. Concrete will not spill into the cable trench to form hard concrete blocks due to the large size of the discharge port, preventing the bottom plate of the cable trench from becoming uneven due to the spilled concrete blocks, thus avoiding damage to the laid cables and improving the safety of subsequent cable laying construction.

[0033] above Figure 1-4 The telescopic concrete pouring funnel shown is a specific embodiment of the present invention, which has embodied the outstanding substantial features and remarkable progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
