DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the accompanying Figures 1-4 The present application is further described in detail.

[0026] The embodiment of the present application discloses a pouring and conveying pipe fixed on a structural steel pipe, referring to Figure 1The pouring conveying pipe fixed on the structural steel pipe comprises a pouring pipe 1, a hoop 2, a mounting plate 3, a sleeve 4 and a fixing mechanism, the mounting plate 3 is a rectangular steel plate, the hoop 2 and the sleeve 4 are respectively mounted on two sides of the mounting plate 3. The hoop 2 is a common steel pipe hoop 2, the hoop 2 is detachably mounted on the structural steel pipe, the structural steel pipe is a reinforcing pipe in a reinforcing cage, the sleeve 4 is a hollow cylindrical pipe body, and the sleeve 4 is rotatably mounted on the mounting plate 3 through a hinge seat 5, and the sleeve 4 can be adjusted in angle through the hinge seat 5. The hoop 2, the mounting plate 3 and the sleeve 4 are mounted on a plurality of structural steel pipes, the plurality of sleeves 4 are obliquely arranged, the mounting positions of the plurality of hoops 2 are adjusted and the angles of the plurality of sleeves 4 are adjusted through the hinge seat 5, so that the plurality of sleeves 4 are located on the same oblique straight line, and the pouring pipe 1 is obliquely and slidably arranged in the plurality of sleeves 4. The fixing mechanism is arranged in the sleeve 4 and connected with the pouring pipe 1 inserted into the sleeve 4, and the fixing mechanism is used for fixedly connecting the pouring pipe 1 in the sleeve 4. When the concrete is poured, the concrete is lifted by a hopper, the lower end of the hopper is connected with the top end of the pouring pipe 1, and then the concrete is poured to the bottom of the reinforcing cage through the inclined pouring pipe 1, and after the pouring is completed, the pouring pipe 1 can be directly reserved in the concrete.

[0027] In the process of binding the reinforcing cage, the plurality of hoops 2 are sequentially mounted on the plurality of structural steel pipes from bottom to top, and the plurality of sleeves 4 are located on the same oblique straight line, when the pouring of the bearing column is needed after the formwork is installed in place, the pouring pipe 1 is obliquely inserted into the plurality of sleeves 4, and the fixing mechanism in the sleeve 4 fixes the pouring pipe 1 at this time; the outlet of the hopper is connected with the top end of the pouring pipe 1 during pouring, so that the concrete is poured to the bottom of the reinforcing cage through the inclined pouring pipe 1, the pouring pipe 1 plays a role of buffering and guiding the concrete, avoids the direct falling of the concrete with high drop to cause segregation, and improves the pouring quality of the concrete.

[0028] Referring to Figure 2 and Figure 3The fixing mechanism comprises a first clamping block 61, a second clamping block 62 and a driving assembly. A first clamping groove 41 and a second clamping groove 42 which are identical in structure but opposite in direction are oppositely formed on the inner wall of the sleeve 4 along the axial direction of the sleeve 4. The bottom walls of the first clamping groove 41 and the second clamping groove 42 are both obliquely arranged, and the shallowest ends of the first clamping groove 41 and the second clamping groove 42 are close to or away from each other. The first clamping block 61 is slidingly arranged in the first clamping groove 41. The side of the first clamping block 61 away from the axial line of the sleeve 4 is parallel to the bottom wall of the first clamping groove 41, and the side of the first clamping block 61 close to the axial line of the sleeve 4 is parallel to the inner wall of the sleeve 4. The second clamping block 62 is slidingly arranged in the second clamping groove 42. The side of the second clamping block 62 away from the axial line of the sleeve 4 is parallel to the bottom wall of the second clamping groove 42, and the side of the second clamping block 62 close to the axial line of the sleeve 4 is parallel to the inner wall of the sleeve 4. The first clamping block 61 and the second clamping block 62 are identical in structure and oppositely arranged. The thickness of the first clamping block 61 and the second clamping block 62 is smaller than the depth of the deepest end of the first clamping groove 41 and the second clamping groove 42, and greater than the depth of the shallowest end of the first clamping groove 41 and the second clamping groove 42. The driving assembly is arranged on the sleeve 4 and connected with the first clamping block 61 and the second clamping block 62. The driving assembly is used to drive the first clamping block 61 and the second clamping block 62 to move close to or away from each other.

[0029] The driving assembly drives the first clamping block 61 and the second clamping block 62 to move close to or away from each other. Since the shallowest ends of the first clamping groove 41 and the second clamping groove 42 are close to or away from each other, when the first clamping block 61 and the second clamping block 62 move, the first clamping block 61 and the second clamping block 62 simultaneously have the tendency to protrude from the inner wall of the sleeve 4 or sink into the inner wall of the sleeve 4. When the first clamping block 61 and the second clamping block 62 have the tendency to protrude from the inner wall of the sleeve 4, the first clamping block 61 and the second clamping block 62 clamp the pouring pipe 1 in the sleeve 4. Figure 3 At this time, no matter whether the pouring pipe 1 moves left or right in the sleeve 4 along the axial direction, one of the first clamping block 61 or the second clamping block 62 limits the movement of the pouring pipe 1, so as to fix the pouring pipe 1 in the sleeve 4.

[0030] Referring to Figure 3The driving assembly comprises a bidirectional screw rod 71, a connecting rod 72, and a rotating member. The bidirectional screw rod 71 is arranged in the sleeve 4 in the axial direction of the sleeve 4 and opposite to the first clamping groove 41 and the second clamping groove 42. The two ends of the bidirectional screw rod 71 are threadedly sleeved with the connecting rod 72. The sleeve 4 is provided with two accommodating cavities 43, which are communicated with the first clamping groove 41 and the second clamping groove 42 respectively. The screw rod passes through the two accommodating cavities 43. The two connecting rods 72 are slidably arranged in the two accommodating cavities 43 respectively. The two connecting rods 72 are threadedly passed through the two ends of the bidirectional screw rod 71 respectively and connected with the first clamping block 61 and the second clamping block 62 respectively. It should be noted that the width of the accommodating cavity 43 is smaller than the width of the first clamping block 61 and the second clamping block 62. The connecting rod 72 is a spring telescopic rod. The telescopic section of the spring telescopic rod always has a tendency to recover under the action of the spring, so that one side of the first clamping block 61 always keeps in close contact with the bottom wall of the first clamping groove 41 and one side of the second clamping block 62 always keeps in close contact with the bottom wall of the second clamping groove 42. The rotating member is arranged on the sleeve 4 and connected with the bidirectional screw rod 71. The rotating member is used to drive the bidirectional screw rod 71 to rotate.

[0031] With reference to Figure 3 and Figure 4 The rotating member comprises a driving gear ring 81, a driven gear 82, and a dial block 83. The driving gear ring 81 is coaxially arranged at one end of the sleeve 4. The inner diameter of the driving gear ring 81 is the same as the inner diameter of the sleeve 4. The driven gear 82 is coaxially arranged at one end of the bidirectional screw rod 71 close to the driving gear ring 81. The driven gear 82 is engaged with the driving gear ring 81. A first insertion slot 811 is formed in the inner wall of the driving gear ring 81 in the axial direction. A second insertion slot 44 corresponding to the first insertion slot 811 is formed in the inner wall of the sleeve 4 in the axial direction. The dial block 83 is arranged on the outer wall of the pouring pipe 1. The size of the dial block 83 is adapted to the first insertion slot 811 and the second insertion slot 44. A plurality of dial blocks 83 are arranged on the outer wall of the pouring pipe 1 at intervals. The spacing between the plurality of dial blocks 83 is the same as the spacing between the plurality of sleeves 4.

[0032] The pouring pipe 1 is inserted into the plurality of sleeves 4, and the dial block 83 is located in the first insertion slot 811 on the driving gear ring 81. At this time, the sleeve 4 is rotated to drive the plurality of driving gear rings 81 to rotate synchronously. The driving gear ring 81 drives the driven gear 82 to rotate when the driving gear ring 81 rotates, thereby driving the bidirectional screw rod 71 to rotate, and further driving the first clamping block 61 and the second clamping block 62 at the two ends of the bidirectional screw rod 71 to move close to or away from each other, thereby realizing the fixation of the sleeve 4.

[0033] With reference to Figure 3 and Figure 4The first clamping blocks 61, the second clamping blocks 62, the bidirectional lead screws 71 and the connecting rods 72 are all provided with a plurality of sets on the sleeve pipes 4, and a plurality of sets of the first clamping grooves 41 and the second clamping grooves 42 are also provided in the sleeve pipes 4, the plurality of bidirectional lead screws 71 are all in meshing connection with the driving gear rings 81 through the driven gear wheels 82, so that when the driving gear rings 81 rotate, a plurality of sets of the first clamping blocks 61 and the second clamping blocks 62 are driven to move close to or away from each other, the plurality of sets of the first clamping blocks 61 and the second clamping blocks 62 clamp the pouring pipes 1, and the fixing effect of the pouring pipes 1 is improved. The third insertion grooves 812 are also provided on the inner wall of the driving gear rings 81 in the circumferential direction, the third insertion grooves 812 are in communication with the first insertion grooves 811, the third insertion grooves 812 are also matched with the push blocks 83, when the pouring pipes 1 drive the driving gear rings 81 to rotate, the push blocks 83 are opposite to the third insertion grooves 812 and rotate into the third insertion grooves 812, so that when the driving gear rings 81 rotate, the pouring pipes 1 will not relatively displace in the axial direction with the sleeve pipes 4, and the driving gear rings 81 are conveniently driven to rotate.

[0034] The implementation principle of the pouring conveying pipe fixed on the structural steel pipe in the embodiment of the application is as follows: in the process of binding the reinforcement cage, a plurality of hoops 2 are sequentially installed on a plurality of structural steel pipes from bottom to top, and the plurality of sleeve pipes 4 are located on the same inclined straight line, when the formwork is installed in place and the pouring of the bearing column is required, the pouring pipe 1 is inserted into the plurality of sleeve pipes 4 in an inclined manner, and the fixing mechanism in the sleeve pipe 4 fixes the pouring pipe 1 at this time; the outlet of the hopper is connected with the top end of the pouring pipe 1, so that the concrete is poured to the bottom of the reinforcement cage through the inclined pouring pipe 1, the pouring pipe 1 plays a role of buffering and guiding the flow of the concrete, avoids the direct falling of the concrete with high falling difference and causes segregation, and improves the pouring quality of the concrete.
