On the other hand, the fixed contact surface cannot be effectively adjusted, and the distribution of the force application area of the pipe may be uneven, especially during a long transportation process, which may cause damage and deformation in the local area of the pipe.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0025] The embodiment provides a pipe placing device for water supply and drainage engineering construction, as shown in Figures 1 to 7As shown, including the back plate 1 along the vertical direction sliding assembly, the middle of the back plate 1 is provided with a through feed inlet 2, in the embodiment, the back plate 1 is assembled on the rack 5 through the guide rail, sliding block along the vertical direction, the inside of the rack 5 is installed with the hydraulic cylinder 6, the piston rod of the hydraulic cylinder 6 and the back plate 1 are fixedly connected, the back plate 1 is driven to do linear motion in the vertical direction through the extension and contraction of the piston rod of the hydraulic cylinder 6; the side end face of the back plate 1 is slidably assembled with two first movable plates 3 vertically symmetrically arranged with the feed inlet 2 as the center, the two first movable plates 3 are rotatably installed with horizontal rollers 4 at the end close to each other; when placing the pipe, the whole device is moved so that the feed inlet 2 is connected to the outlet of the pipe conveying mechanism, when the pipe is conveyed into the feed inlet 2, the two horizontal rollers 4 do linear motion close to each other along the vertical direction and form clamping to the pipe placed in the feed inlet 2, then the hydraulic cylinder 6 is started, the pipe is lifted to the position level with the placing point, then the pipe is manually transferred to the placing point, during the whole lifting process of the pipe, since the pipe only bears the clamping force on the upper and lower sides, horizontal displacement is easily caused during the lifting process, and then safety hazard is formed, therefore, in the embodiment, the other side end face of the back plate 1 is slidably assembled with two second movable plates 7 horizontally symmetrically arranged with the feed inlet 2 as the center, the two second movable plates 7 are rotatably installed with vertical rollers 8 at the end close to each other; when the two horizontal rollers 4 do linear motion close to each other along the vertical direction, the two vertical rollers 8 do linear motion close to each other in the horizontal direction, the pipe is clamped in the horizontal direction, the displacement of the pipe in the horizontal direction is avoided, and the stability of the pipe during the lifting process is improved.

[0026] On the basis of the above scheme, the mutual approaching linear motion of the two horizontal rollers 4 in the vertical direction is driven by a connecting rod structure. Specifically, the horizontal roller 4 is fixedly sleeved on a rotating shaft 42, both ends of the rotating shaft 42 are rotatably installed on a bearing seat, the bearing seat is fixedly connected with the first movable plate 3, one end of the rotating shaft 42 is rotatably connected with a connecting rod 43, the other ends of the two connecting rods 43 are hingedly connected through a hinge shaft 44, and the electric cylinder 45 is fixedly installed on the back plate 1, the piston rod of the electric cylinder 45 is rotatably connected with the hinge shaft 44; when the pipe is located between the two horizontal rollers 4, the electric cylinder 45 is started, the piston rod of the electric cylinder 45 is elongated and drives the hinge shaft 44 to move away from the back plate 1, at the same time, the hinge shaft 44 drives the two connecting rods 43 to rotate towards each other, since the first movable plate 3 can only slide in the vertical direction, the two horizontal rollers 4 are driven by the connecting rods 43 to move linearly towards each other, until the horizontal roller 4 is in close contact with the pipe, that is, the clamping of the pipe in the vertical direction is completed; similarly, the mutual approaching linear motion of the two vertical rollers 8 in the horizontal direction is also driven by a connecting rod structure, and the same principle is adopted, the pipe is clamped in the horizontal direction by the two vertical rollers 8, so that the horizontal displacement of the pipe during lifting is avoided.

[0027] In order to improve the motion stability of the hinge shaft 44, in the embodiment, the electric cylinder 45 is fixedly installed on a guide plate 46, the guide plate 46 is fixedly connected with the back plate 1, a guide groove parallel to the axial direction of the piston rod of the electric cylinder 45 is formed in the guide plate 46, and the hinge shaft 44 is slidably assembled in the guide groove.

[0028] During the lifting of the pipe, the pipe under the action of its own weight will form a pressure on the lower horizontal roller 4, if the lifting operation is maintained for a long time, the contact position of the pipe and the horizontal roller 4 is easy to form a depression, which not only causes the quality of the appearance of the pipe to decrease, but also causes the pipe to be damaged, therefore, in the embodiment, the two horizontal rollers 4 are inclinedly arranged on the horizontal plane, the two vertical rollers 8 are inclinedly arranged on the vertical plane, the two horizontal rollers 4 are synchronously and reversely rotated, the two vertical rollers 8 are synchronously and reversely rotated, and the directions of the components of the two horizontal rollers 4 and the two vertical rollers 8 in the axial direction are consistent; after the rollers are arranged in an inclined manner, the rollers will form components in the axial direction of the pipe and the radial direction of the pipe during rotation, wherein the components in the axial direction of the pipe are offset, and the components in the radial direction of the pipe will drive the pipe to rotate, during the clamping and lifting of the pipe, the components of the two horizontal rollers 4 and the two vertical rollers 8 in the radial direction of the pipe jointly drive the pipe to rotate along its own axial direction, so that the contact position of the pipe and the horizontal roller 4 is changed in real time, thereby reducing the problem of uneven force of the pipe and effectively reducing the probability of the pipe being depressed under the action of its own weight.

[0029] On the basis of the above scheme, two transverse rollers 4 need to keep synchronous reverse rotation when doing linear motion in vertical direction, in the embodiment, the rotating shaft 42 is connected with a connecting shaft 422 through the universal coupling 421, the power of the rotating shaft 42 in the inclined state is transmitted to the connecting shaft 422 in the horizontal state through the universal coupling 421, the connecting shaft 422 and the connecting rod 43 are rotationally connected, the gear set 423 is transmissionally connected between one of the connecting shafts 422 and the hinged shaft 44, and the gear set 423 is arranged on the connecting rod 43; the first synchronous wheel 424 is fixedly sleeved on the outer circumferential surface of the hinged shaft 44, the second synchronous wheel 425 is fixedly sleeved on the outer circumferential surface of the other connecting shaft 422, and the synchronous belt 426 is sleeved between the first synchronous wheel 424 and the second synchronous wheel 425; the motor 427 is further included, the motor shaft of the motor 427 is fixedly connected with one of the rotating shafts 42, and the motor 427 is fixedly installed on the first movable plate 3; when the two transverse rollers 4 are in close contact with the pipe fittings, the motor 427 is started, the motor shaft of the motor 427 drives one of the transverse rollers 4 to rotate, the connecting rod 43 further drives the hinged shaft 44 to reversely rotate, the hinged shaft 44 drives the first synchronous wheel 424 to reversely rotate, the first synchronous wheel 424 drives the second synchronous wheel 425 to synchronously reversely rotate through the synchronous belt 426, and the second synchronous wheel 425 drives the other transverse roller 4 to synchronously reversely rotate.

[0030] In addition, in order to increase the friction between the roller and the pipe fitting, in the embodiment, the outer circumferential surfaces of the transverse rollers 4 and the vertical rollers 8 are sleeved with rubber sleeves 41, the outer circumferential surfaces of the rubber sleeves 41 are provided with spiral guide bars, the spiral direction of the guide bars is matched with the rotating direction of the rollers, when the rubber sleeves 41 contact the pipe fittings, due to the softness of the rubber sleeves 41, the contact area between the rubber sleeves 41 and the pipe fittings is compressed, the contact area between the rubber sleeves 41 and the pipe fittings is increased, and the pipe fittings are subjected to a radial component force through the rotating guide bars, so that the pipe fittings are caused to rotate.
