With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] In actual use of the device, when the sounding hammer falls rapidly and collides with the foundation, the foundation fragments formed by the impact will splash outward. Since the device lacks an integrated structure to contain the debris, the splashing fragments can easily pose a threat to the safety of the operators. For this reason, we provide a foundation bearing capacity detection device. Utility Model Content

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. Example

[0026] Please combine Figure 1-3 , a foundation bearing capacity detection device of this embodiment includes:

[0027] A bracket 1, a probe rod 2 is arranged on the inner side of the bracket 1 and the top of the probe rod 2 passes through the bracket 1, a roller 3 is rotatably connected to the top of the bracket 1, one end of the roller 3 is coaxially fixedly connected to a motor, a rope 4 is wound around the outside of the roller 3 and the end of the rope 4 is fixedly connected to the top of the probe rod 2, a guide wheel 5 is rotatably connected to one side of the roller 3 and the surface of the guide wheel 5 is in contact with the rope 4, which can ensure that the probe rod 2 can stably move vertically;

[0028] The anti-debris splashing assembly includes four groups of fixed plates 101 fixedly connected to the bracket 1, and a movable plate 102 is movably connected above the fixed plate 101. Multiple groups of folding plates 103 are hinged between the movable plate 102 and the fixed plate 101. Guide blocks 106 are fixedly installed on both sides of the movable plate 102. Guide grooves are provided at positions corresponding to the guide blocks 106 on the bracket 1 and are slidably connected to the guide blocks 106, which can guide the vertical movement of the movable plates 102. Two adjacent groups of movable plates 102 are fixedly connected by a connecting frame 109, so that the four groups of movable plates 102 can move simultaneously.

[0029] Four groups of winding rollers 104 are symmetrically connected to the top of the bracket 1 for rotation. A pull rope 105 is wound around the outside of the winding roller 104 and the end of the pull rope 105 is fixedly connected to the movable plate 102. One end of two groups of winding rollers 104 on one side are coaxially fixedly connected with a transmission gear 1, and the two groups of transmission gears 1 are connected by a transmission toothed belt 107. One end of the roller 3 and one end of the winding roller 104 on one side are coaxially fixedly connected with a transmission gear 2, and the two groups of transmission gears 2 are connected by a transmission toothed belt 108. The two groups of winding rollers 104 on the same horizontal line are fixedly connected by a connecting shaft, so that the motor can drive the four groups of winding rollers 104 to rotate while driving the roller 3 to rotate, thereby reducing the energy consumption of the device.

[0030] The implementation principle of a foundation bearing capacity detection device in the embodiment of the present application is as follows: first, the bracket 1 is placed at the position to be detected, and then the motor is started, and the roller 3 is driven by the motor to rotate to release the rope 4. At this time, the probe rod 2 will fall vertically, and the tip of the bottom of the probe rod 2 will contact and collide with the foundation for detection. At the same time, the transmission gear 1 and the transmission toothed belt 1 107 are matched, and the transmission gear 2 and the transmission toothed belt 2 108 are matched, so that the four sets of winding rollers 104 can be driven to rotate at the same time to reel the pull rope 105, and the guide block 106 and the guide block 106 are connected. With the sliding cooperation towards the groove, the movable plates 102 on both sides can be driven to move vertically upward, and with the connection cooperation of the connecting frame 109, the movable plates 102 on the other two sides can also be driven to move vertically upward, so that the folded folding plates 103 can be unfolded to automatically cover the four sides of the bracket 1, effectively avoiding the problem that the flying debris easily poses a threat to the health safety of the operators due to the lack of an integrated structure that can enclose the debris. Finally, the motor is controlled to reverse to retract the probe rod 2, and the damage to the foundation can be observed after the device is removed. Example

[0031] The present embodiment is further improved on the basis of the embodiment 1 in that: a cross bar 201 is slidably connected to a movable plate 102 on one side and a movable plate 102 parallel thereto, an arc plate 202 is fixedly connected to the end of the cross bar 201, a cleaning cotton is added to the inner side of the arc plate 202, a spring 203 is sleeved on the outer side of the cross bar 201, and both sides of the arc plate 202 are fixedly connected to a limit rod 204, and the limit rod 204 is slidably connected to the movable plate 102, which can prevent the arc plate 202 from deflecting and keep it in a horizontal state at all times. The two sets of arc plates 202 can be spliced ​​into a complete circle, and the diameter of the circle matches the diameter of the probe rod 2, so that the probe rod 2 can pass through smoothly. , the elastic effect of the spring 203 and the sliding cooperation between the cross bar 201 and the movable plate 102 are utilized to enable the two groups of arc plates 202 to maintain contact. After the detection is completed, the motor is controlled to reverse, and the motor drives the roller 3 to rotate to reel in the rope 4. At this time, the four groups of reel rollers 104 will release the pull rope 105. When the rope 4 is reeled in, it will drive the probe rod 2 to move vertically upward. When the pull rope 105 is released, the movable plate 102 will move vertically downward under the action of gravity. The downward movement of the movable plate 102 drives the arc plate 202 to move downward. The probe rod 2 and the two groups of arc plates 202 move in opposite directions to each other, so that the cleaning cotton can wipe off the dust and debris attached to the surface of the probe rod 2 after use, so as to facilitate the next use.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
