DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Example 1

[0021] See also Figure 1 , Figure 4 The utility model shows a steel pipe feeding device for construction, comprising a base 1, a power frame 2 is arranged on the top of the base 1, a power transmission belt 3 and a motor 4 for driving the power transmission belt 3 to rotate are arranged on the power frame 2, two vertically arranged support columns 5 are arranged on the top of the base 1 on the left and right sides of the power frame 2, a vertically arranged screw rod 6 is rotatably arranged between the two support columns 5 on the same side, the tops of the two screw rods 6 are both driven with gears 28, the two gears 28 are connected by a chain 7, and the top of one of the screw rods 6 penetrates the gear 28 and is driven with a rotating disk 8 , the middle parts of the two screw rods 6 are threadedly connected with sliders 9, and the two sliders 9 are connected to the same mounting frame 10 near one end, and a passive transmission belt 11 is provided on the mounting frame 10. A plurality of contact members 12 with V-shaped outer sides are arranged at even intervals on the outer peripheral surfaces of the power transmission belt 3 and the passive transmission belt 11; it should be noted that the side of the contact member 12 in contact with the steel pipe is the outer side, the passive transmission belt 11 is vertically arranged above the power transmission belt 3, and the V-shaped outer side surface of the contact member 12 on the power transmission belt 3 is aligned with the V-shaped outer side surface of the contact member 12 on the passive transmission belt 11.

[0022] By setting a screw rod 6, a chain 7, a gear 28 and a rotating disk 8, the rotating disk 8 drives the screw rod 6 to rotate, and under the action of the slider 9 and the screw rod 6 threaded engagement, the passive transmission belt 11 can be driven to descend, which is convenient for vertical adjustment of the passive transmission belt 11, and is used to change the spacing between the passive transmission belt 11 and the power transmission belt 3, so as to adapt to steel pipes of different diameters. At the same time, the chain 7 cooperates with the gear 28 to drive the other screw rod 6 to rotate, thereby ensuring the synchronization of the rotation of the two screw rods 6, and then ensuring the stable movement of the passive transmission belt 11 in the vertical position, wherein the outer side surface of the contact piece 12 is V-shaped, which increases the contact area between the contact piece 12 on the power transmission belt 3 and the contact piece 12 on the passive transmission belt 11 and the steel pipe, increases the actual force on the steel pipe, makes the transmission more stable, and prevents slipping.

[0023] When the present solution is in use, the steel pipe to be transmitted is placed on the power transmission belt 3, and the rotating disk 8 is rotated to drive the screw 6 to rotate, and finally the passive transmission belt 11 is driven to descend, so that the contact pieces 12 on its outer peripheral surface and the contact pieces 12 on the power transmission belt 3 can clamp the steel pipe up and down, and the power transmission belt 3 is driven to move under the action of the motor 4, so that the steel pipe is transported synchronously with the power transmission belt 3, thereby realizing the transportation of steel pipes of different diameters.

[0024] As a preferred embodiment, see Figure 1 As shown, two auxiliary blocks 13 are provided on the left and right sides of the mounting frame 10, and the two auxiliary blocks 13 are arranged near the front and rear ends of the mounting frame 10. The two auxiliary blocks 13 on the same side are connected to the same connecting column 14 at one end away from the mounting frame 10, and the slider 9 is fixedly connected to the connecting column 14 at one end away from the mounting frame 10; by arranging the auxiliary blocks 13 and the connecting column 14, the two ends of the mounting frame 10 can be provided with auxiliary support, thereby improving the stability of the passive transmission belt 11.

[0025] As a preferred embodiment, see Figure 1As shown, a scale line 15 is vertically provided on one side of the support column 5 close to the auxiliary block 13, and a corresponding mark can be set on the scale line 15. An indication arrow 16 pointing horizontally to the scale line 15 is provided on the top side of the auxiliary block 13. It should be noted that the indication arrow 16 cooperates with the scale line 15, and the scale line 15 is set according to the spacing between the passive transmission belt 11 and the power transmission belt 3 for transmitting steel pipes of different diameters; for example, in actual use, the marks on the scale line 15 are 10cm, 15cm, 20cm, etc., respectively. When the indication arrow 16 on the auxiliary block 13 is aligned with the scale line marked as 10cm, the spacing between the power transmission belt 3 and the passive transmission belt 11 is suitable for conveying a steel pipe with a diameter of 10cm. When the steel pipe with a diameter of 15cm is transmitted, only It is necessary to adjust the indicator arrow 16 on the auxiliary block 13 to be horizontally aligned with the scale line marked as 15 cm, so that the passive transmission belt 11 can be moved to a suitable position, so that the spacing between the power transmission belt 3 and the passive transmission belt 11 is suitable for conveying steel pipes with a diameter of 15 cm, so that the contact pieces 12 on its outer peripheral surface and the contact pieces 12 on the power transmission belt 3 can clamp the steel pipe up and down, and the power transmission belt 3 is driven to move under the action of the motor 4, and the steel pipe is transported synchronously with the power transmission belt 3. By setting the scale line 15 to match the indicator arrow 16, it is convenient to quickly adjust the passive transmission belt 11 to a suitable position. It should be noted that the mark on the scale line 15 can be set according to the spacing between the passive transmission belt 11 and the power transmission belt 3 according to actual application conditions.

[0026] During use of the present solution, when transmitting steel pipes of different diameters, the cooperation of the scale line 15 and the indicator arrow 16 facilitates the rapid adjustment of the passive transmission belt 11 to a suitable vertical position, so as to ensure that the contact pieces 12 on the outer peripheral surface of the passive transmission belt 11 and the contact pieces 12 on the power transmission belt 3 can clamp the steel pipe up and down, so that the steel pipe is transported synchronously with the power transmission belt 3, and prevent the passive transmission belt 11 from being adjusted too high in the vertical direction, resulting in insufficient clamping force on the steel pipe, reducing the force acting on the steel pipe and causing slipping, and avoid the passive transmission belt 11 from being adjusted too low in the vertical direction, resulting in excessive clamping force on the steel pipe by the contact pieces 12 on the outer peripheral surface of the passive transmission belt 11 and the contact pieces 12 on the power transmission belt 3, which affects the synchronous transportation of the steel pipe with the power transmission belt 3.

[0027] Example 2

[0028] Based on the above-mentioned embodiment 1, refer to Figure 1 It is shown that a connecting block 17 arranged at the same level is connected between the tops of the two support columns 5 respectively located on the left and right sides of the power frame 2, the top of the screw rod 6 passes through the connecting block 17 through a supporting bearing 18, and is connected through a chain 7 transmission, and the bottom of the screw rod 6 is rotatably connected to the top of the base 1 through a connecting bearing 19; by setting the supporting bearing 18 and the connecting bearing 19, the smoothness and stability of the rotation of the screw rod 6 are guaranteed.

[0029] As a preferred embodiment, see Figure 2 As shown, a slide groove 20 is provided on the top of the connecting block 17, a limiting ring 21 is provided at the notch of the slide groove 20, a limiting nail 22 is slidably provided in the slide groove 20, the bottom end of the limiting nail 22 is connected to a conical transmission block 23, the top of the limiting nail 22 passes through the notch of the slide groove 20 and passes out of the slide groove 20, a threaded hole 24 connected to the slide groove 20 is provided on the outer side of the connecting block 17, a bolt 25 is threadedly connected to the threaded hole 24, and one end of the bolt 25 placed in the slide groove 20 is connected to a conical driving block 26. It should be noted that the notch of the slide groove 20 is opposite to the bottom side of the rotating disk 8, and the outer ring diameter of the top of the transmission block 23 is larger than the inner ring diameter of the limiting nail 22 to prevent the limiting nail 22 from sliding out of the slide groove 20.

[0030] See also Figure 2 , Figure 3 As shown, when the present solution is in use, when the rotating disk 8 drives the screw rod 6 to rotate, under the action of the slider 9 and the screw rod 6 threaded engagement, the passive transmission belt 11 is driven to move to a suitable position, and by rotating the bolt 25, the arc surface of the driving block 26 enters the slide groove 20 and slides against the arc surface of the transmission block 23, thereby pushing the limiting nail 22 to move upward, so that the top end of the limiting nail 22 contacts the bottom side of the rotating disk 8, and the rotating disk 8 is locked, so as to limit the screw rod 6 and prevent the contact piece 12 on the passive transmission belt 11 from mating with the contact piece 12 on the power transmission belt 3. When clamping the steel pipe, the passive transmission belt 11 is subjected to force, so that the slider 9 and the screw rod 6 are threadedly engaged, and the passive transmission belt 11 follows the movement to avoid that the contact piece 12 on the passive transmission belt 11 and the contact piece 12 on the power transmission belt 3 cannot clamp the steel pipe well, resulting in insufficient clamping force, which reduces the force acting on the steel pipe and causes slipping. Conversely, when it is necessary to rotate the rotating disk 8, the bolt 25 is rotated in the opposite direction to move the drive block 26 out of the slide groove 20, and the limit pin 22 slides down under the action of gravity, and its top end no longer contacts the bottom side of the rotating disk 8.

[0031] As a preferred embodiment, see Figure 4 As shown, a rubber block 27 is convexly provided on the outer side surface of the contact piece 12. By providing the rubber block 27, the friction between the outer side surface of the contact piece 12 and the steel pipe is increased, thereby improving the stability of transmission.
