Description

Technical Field

[0001] The utility model relates to the technical field of hole digging equipment, in particular to a building foundation pit construction equipment. Background Art

[0002] A deep foundation pit refers to an engineering project with an excavation depth exceeding 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. During the construction of an existing deep foundation pit, a foundation pit retaining structure is required to provide a temporary retaining wall structure for the deep foundation pit. The foundation pit retaining structure uses a (pile) wall to withstand the earth pressure and water pressure generated by the unloading of the foundation pit excavation. An embedded block is provided at the bottom of the existing (pile) wall. The embedded block is embedded into the ground to complete the installation and fixation of the (pile) wall. When embedding the embedded block into the ground, excavation is required. The equipment digs a pit on the ground that matches the embedded block, and then a hole-digging device is needed. For example, the patent website discloses a drilling device for building foundation pit construction (publication number: CN216841429U). The worker of this device pushes the device to move by a push rod, but the height of the push rod is certain. If the worker is too tall, he needs to bend down to hold the push rod with his hand. Then, when pushing the device, the worker needs to bend down all the time, which will cause damage to the worker's waist. Therefore, the technical personnel in this field proposed a building foundation pit construction equipment. Utility Model Content

The height of the push rod 12 can be adjusted to adapt to workers of different heights;

[0024] When the device is running, the first motor 15 and the second motor 19 are turned on, the running first motor 15 drives the second screw 16 to rotate, the rotating second screw 16 drives the threaded seat 17 to descend, and the descending threaded seat 17 drives the digging mechanism to descend, and at the same time the running second motor 19 drives the digging rotating rod 20 to rotate, after the lower end of the rotating and descending digging rotating rod 20 passes through the opening 21 and contacts the ground, the drilling and digging operation can be carried out, and then the digging rotating rod 20 continues to descend until the required depth is reached, after which the second motor 19 is turned off, and the first motor 15 drives the second screw 16 to reverse and drive the digging mechanism to rise through the above operation until its position is restored;

[0025] The running semiconductor refrigeration plate 24 cools the water in the water tank 23. When the second motor 19 is running, the water pump 25 will also run. The running water pump 25 draws the cold water in the water tank 23 and sends it into the threaded tube 22 through the first telescopic hose 26. The cold water flowing through the threaded tube 22 absorbs the heat generated by the operation of the second motor 19 and becomes warm water. After that, the warm water returns to the water tank 23 through the second telescopic hose 27 to continue to be conditioned by the semiconductor refrigeration plate 24, so that the heat generated by the second motor 19 can be quickly dissipated, ensuring that the temperature around the second motor 19 is not too high, thereby extending the service life of the second motor 19.
