[0015] (3) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] In this invention, when different height points are involved in pipeline installation, personnel can start a dual-head motor to rotate the transmission rods and their respective first bevel gears connected at both ends. At this time, the second bevel gear meshing with the two gears can drive the transmission screw to rotate synchronously. Thus, the first screw sleeve acting with the two screws can synchronously carry the mounting frame, support frame, upper work platform, protective cover frame, and four sets of guide sleeve frames and the first guide rod to rise stably. Since the traction mechanism is located above the upper work platform, the height of the pipeline to be installed can be adjusted. The protective cover frame is always covered around the main body, so it can prevent external dust and impurities from entering the main body during lifting and subsequent pipeline installation, thus providing better protection for the corresponding mechanical components.
[0018] In this invention, the operator manually cranks the screw rods to rotate them in both directions. At this time, the two second screw sleeves that interact with the screw rods can move relative to each other with their respective fixed clamping plates and guided by the second guide rod. When the distance between the two plates is approximately the same as the size of the PE pipe to be installed, the operator can place the PE pipe between the two plates and on the upper surface of the guide wheel frame. After placement, the operator can manually crank the screw rods again to clamp and stabilize the pipe with the two plates. Then, the operator can move the main body to the installation point. When installation is required, the two plates can be slightly loosened, and the operator can use the mobility of the guide wheel frame to pull the PE pipe for subsequent installation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This specific embodiment is an adjustable traction machine, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the device includes a main body 1, a handheld bracket 2 fixed to one side of the main body 1, and an adjustment mechanism 3 installed inside and above the main body 1. The adjustment mechanism 3 includes a fixed plate 31 and an upper work platform 33, and an upper frame 4 fixed above the upper work platform 33. A traction mechanism 5 is installed inside and above the upper frame 4. The fixed plate 31 is fixed inside the main body 1, and an adjustment assembly 32 is installed on the upper and lower parts of the fixed plate 31. The adjustment assembly 32 includes a dual-head motor 321, which is installed below the fixed plate 31. The two ends of the dual-head motor 321 are connected to... There are two transmission rods 322, and a first bevel gear 323 is fixedly mounted on a section of each of the two transmission rods 322. A second bevel gear 324 meshes with one side of each of the two first bevel gears 323, and a transmission screw 325 is fixedly mounted in the middle of each of the two second bevel gears 324. A first screw sleeve 326 is screwed onto the periphery of one side of each of the two transmission screws 325, and a mounting bracket 327 is fixedly mounted on the inner side of each of the two first screw sleeves 326. Support brackets 328 are fixedly mounted on the four sides of the mounting brackets 327, and a guide sleeve bracket 329 is fixedly mounted on a section of each of the four support brackets 328. A fixing plate 3... A first guide rod 3210 is fixedly installed on the four sides of the upper part of the main body 1. The first guide rod 3210 is connected to a guide sleeve 329 fixedly installed on the support frame 328 by a movable guide connection. A protective cover 34 is fixedly installed around the periphery of the upper work platform 33. The protective cover 34 covers the periphery of the main body 1. When different height points are involved in the pipeline installation process, the personnel can start the double-head motor 321 to make the transmission rod 322 connected at both ends and the first bevel gear 323 of each end rotate. At this time, the second bevel gear 324 meshing with the two gears can drive the transmission screw 325 to move synchronously. Rotation causes the first lead screw sleeve 326, which interacts with the two lead screws, to synchronously carry the mounting frame 327, support frame 328, upper work platform 33, and protective cover frame 34, in coordination with the four sets of guide sleeve frames 329 and the first guide rod 3210, to rise stably. Since the traction mechanism 5 is located above the upper work platform 33, the height of the pipe to be installed can be adjusted. The protective cover frame 34 is always covered around the main body 1, so external dust and impurities can be prevented from entering the interior of the main body 1 during lifting and subsequent pipe installation, thus providing better protection for the corresponding mechanical components.
[0027] The traction mechanism 5 includes a stabilizing component 51, which is installed in the middle and above of the upper frame 4. The stabilizing component 51 includes a preset groove 511, which is located on both sides of the middle of the upper frame 4. A positive and negative lead screw 512 is installed in the middle of one of the preset grooves 511, and a hand crank 513 is connected to one end of the positive and negative lead screw 512. Second lead screw sleeves 514 are screwed on both sides of the middle of the positive and negative lead screw 512. A second guide rod 515 is fixed in the middle of the other preset groove 511. The second guide rod 515 is connected to the clamping plate 52 in a movable guide manner, and the clamping plate 52 is fixed above the second lead screw sleeve 514. A traction guide wheel frame 5 is installed in the middle of the upper part of the upper frame 4. 3. Beforehand, the staff manually cranks the hand crank 513 to rotate the forward and reverse screws 512. At this time, the two second screw sleeves 514 that interact with the screws can move relative to each other with their respective fixed clamping plates 52 and the second guide rods 515. When the distance between the two plates is approximately the same as the size of the PE pipe to be installed, the staff can place the PE pipe between the two plates and on the upper surface of the guide wheel frame 53. After placement, the staff can manually crank the hand crank 513 again to clamp and stabilize the pipe with the two plates. Then, the staff can move the main body 1 to the installation point. When installation is required, the staff can slightly loosen the two plates and use the mobility of the guide wheel frame 53 to pull the PE pipe for subsequent installation.
[0028] Working principle: The operator manually cranks the hand crank 513 to rotate the forward and reverse screws 512. At this time, the two second screw sleeves 514, acting on the screws, can move relative to each other with their fixed clamping plates 52, guided by the second guide rod 515. When the distance between the two plates is approximately equal to the size of the PE pipe to be installed, the operator can place the PE pipe between the two plates and on the upper surface of the guide wheel frame 53. After placement, the operator can manually crank the hand crank 513 again to clamp and stabilize the pipe. Then, the operator can move the main body 1 to the installation point. When installation is required, slightly loosen the two plates and use the mobility of the guide wheel frame 53 to pull the PE pipe for subsequent installation. Later, when different height points are involved in the pipe installation process, the operator can start... The dual-head motor 321 causes the transmission rods 322 connected to its two ends and each of the first bevel gears 323 to rotate. At this time, the second bevel gear 324, which meshes with the two gears, can drive the transmission screw 325 to rotate synchronously. Thus, the first screw sleeve 326, which interacts with the two screws, can synchronously carry the mounting frame 327, support frame 328, upper work platform 33, and protective cover frame 34, and coordinate with the guidance of the four sets of guide sleeve frames 329 and the first guide rod 3210 to rise stably. Since the traction mechanism 5 is located above the upper work platform 33, the height of the pipe to be installed can be adjusted. The protective cover frame 34 is always covered around the main body 1, so it can prevent external dust and impurities from entering the interior of the main body 1 during lifting and subsequent pipe installation, thus providing better protection for the corresponding mechanical parts.
[0029] All technical features in this embodiment can be freely combined according to actual needs.
