DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 7The utility model provides a technical solution: a pile pulling machine for water conservancy project construction, including a pile pulling mechanism 1, a support assembly 2 is arranged under the pile pulling mechanism 1, a cleaning assembly 3 is arranged outside the pile pulling mechanism 1, the support assembly 2 includes a support rod 201, and a threaded groove is provided on the outside of the support rod 201, a sleeve 1 202 is externally threadedly connected to the support rod 201, and a rotating shaft 203 is rotatably connected to the sleeve 1 202, and a sleeve 204 is rotatably connected to the rotating shaft 203, and a supporting foot 205 is rotatably connected to the sleeve 204, and a limiting rod 206 is internally threadedly connected to the sleeve 204, and a limiting block 208 is fixedly connected to the front of the limiting rod 206, and a limiting groove is provided under the supporting foot 205 207, and two limiting grooves 207 are symmetrically opened along the center of the limiting block 208. By setting the support rod 201 and the sleeve 1 202, the sleeve 1 202 is rotated to make the sleeve 1 202 move along the direction of the support rod 201, and the supporting foot 205 is pushed to move, so as to facilitate the adjustment of the height of the support rod 201. By rotating the sleeve 204, the limiting rod 206 is extended from the sleeve 204, so that the limiting rod 206 is engaged with the ground, thereby achieving the fixation of the pile puller. By setting the limiting groove 207 and the limiting block 208, it is ensured that the limiting rod 206 extends from the sleeve 204, and the limiting rod 206 is prevented from rotating together with the sleeve 204.

[0027] The limiting rod 206 is slidably connected to the supporting foot 205 via a limiting block 208 . The pile pulling mechanism 1 comprises a supporting base 101 , and a hydraulic rod 102 is fixedly connected to the supporting base 101 .

[0028] Two hydraulic rods 102 are symmetrically arranged along the center of the support base 101 , and a connecting transverse plate 103 is fixedly connected to the hydraulic rod 102 . A hydraulic pipe interface 104 is provided on the connecting transverse plate 103 , and the hydraulic pipe interface 104 is flange-connected to the hydraulic rod 102 .

[0029] A fixing plate 105 is fixedly connected to the outside of the hydraulic rod 102 , and a pile puller body 106 is fixedly connected to one side of the fixing plate 105 . The support base 101 is fixedly connected to the support rod 201 below, and four support rods 201 are sequentially arranged below the support base 101 .

[0030] The cleaning component 3 includes a baffle 1 301 , and the baffle 1 301 is fixedly connected to the support base 101 at the bottom, and two baffles 1 301 are symmetrically arranged along the center of the support base 101 .

[0031] A slide groove 302 is provided on one side of the baffle 301, and two slide grooves 302 are symmetrically provided along the center of the baffle 301. A slider 308 is provided in the slide groove 302, and a connecting plate 303 is fixedly connected to one side of the slider 308. By providing the baffle 301, foreign matter cleaned is prevented from falling outside the hydraulic rod 102, thereby ensuring the service life of the hydraulic rod 102.

[0032] Two connecting plates 303 are arranged opposite to each other, and a scraper 304 is engaged and connected under the connecting plates 303. A second slide groove 305 is opened on one side of the baffle 1 301, and the second slide groove 305 is arranged below the first slide groove 302. By setting the scraper 304, when the pile body is pulled out, the scraper 304 remains stationary relative to the pile body, thereby completing the cleaning of the pile body surface. The scraper 304 is an arc-shaped plate, which makes it easy for foreign matter to move along the surface of the scraper 304, so that the foreign matter falls on the second baffle 306.

By providing the rubber pad 307, when the pile body is pulled out, it is ensured that foreign matter bonded to the outside of the pile body pushes the rubber pad 307 to bend, thereby ensuring that the foreign matter passes through the rubber pad 307 smoothly. By providing the baffle 2 306, and the baffle 2 306 is an inclined plate, when the cleaned foreign matter falls on the baffle 2 306, the foreign matter moves along the baffle 2 306, thereby preventing the cleaned foreign matter from accumulating and preventing the foreign matter from falling into the hole and causing blockage.

[0034] Working principle: When the pile puller is used, firstly, the external hydraulic device is connected to the hydraulic rod 102 through the hydraulic pipe interface 104, and then the pile puller body 106 is placed on the pile body, and the sleeve 1 202 is rotated to make the sleeve 1 202 move along the direction of the support rod 201, and the sleeve 2 204 is rotated to make the limit rod 206 move along the limit groove 207, so that the limit rod 206 is engaged with the ground, so as to facilitate the adjustment of the height of the pile puller, ensure that the moving direction of the hydraulic rod 102 is parallel to the central axis of the pile body, ensure the use of the pile puller, and prevent the pile puller from deviating during operation, and then, The pile puller body 106 is fixed to the pile body, and the connecting plate 303 and the second baffle plate 306 are moved through the baffle plate 1 301 and the second slide groove 305, so that the scraper plate 304 and the rubber pad 307 overlap the pile body, and then the external hydraulic equipment is started to operate the hydraulic rod 102 and drive the pile puller body 106 to move, so that the pile puller body 106 drives the pile body to move, and keeps the scraper plate 304 and the pile body relatively still, so that the scraper plate 304 cleans the surface of the pile body, and at the same time, the cleaned matter moves along the second baffle plate 306 to prevent the accumulation of foreign matter under cleaning, thereby ensuring the use of the pile puller, and completing the use of the pile puller.

[0035] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
