DETAILED DESCRIPTION

[0028] The embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0029] Example one: as shown in the accompanying drawings, Figure 1 to the accompanying drawings, Figure 6 The utility model provides a highway engineering is with foundation pit shielding protection device, including protective assembly 100, including structural member 101, set up in the extension piece 102 of structural assembly one side, set up in the locking piece 103 of extension piece 102 one side and set up in the supporting piece 104 of structural member 101 one side,

[0030] Structural member 101 includes first protective plate 101a, the inner cavity 101b of being opened in first protective plate 101a one side and the second protective plate 101c of being slidably arranged in first protective plate 101a one side,

[0031] The extension piece 102 comprises a driving motor 102a arranged on one side of the first protective plate 101a, and a threaded rod 102b arranged on an output end of the driving motor 102a, one end of the threaded rod 102b extending into the first protective plate 101a and being threadedly connected with the second protective plate 101c. When it is needed to extend the first protective plate 101a, the driving motor 102a and the threaded rod 102b are arranged to drive the second protective plate 101c to slide outwards, so as to increase the protection area of the protection device, and the size of the protective plate can be adjusted in real time according to the size of the foundation pit.

[0032] Further, the locking piece 103 comprises an adjusting bolt 103a threadedly connected to the lower side of the first protective plate 101a, a locking box 103b rotatably arranged on one side of the adjusting bolt 103a, and a sliding plate 103c slidably arranged in the locking box 103b, a locking block 103d fixedly installed on the upper side of the sliding plate 103c, and a wedge block 103e fixedly installed on the lower side of the second protective plate 101c. The locking piece 103 further comprises a reset spring 103f arranged in the locking box 103b, and the two ends of the reset spring 103f are respectively connected to the side wall of the sliding plate 103c and the inner side wall of the locking box 103b. When the second protective plate 101c slides outwards, the inclined surface of the wedge block 103e is in contact with the inclined surface of the locking block 103d, the locking block 103d is pressed, so as to drive the locking block 103d and the sliding plate 103c to slide downwards. After sliding, the reset spring 103f drives the sliding plate 103c to slide back to reset, and the locking block 103d is re-topped into the tooth gap of the wedge block 103e. At this time, the locking block 103d is in contact with the vertical surface of the wedge block 103e, so as to realize the locking and fixing of the wedge block 103e, complete the locking and fixing of the second protective plate 101c, and improve the stability of the second protective plate 101c.

[0033] Further, when it is needed to recycle the second protective plate 101c, the adjusting bolt 103a is reversely rotated to drive the locking box 103b to slide downwards as a whole, so that the wedge block 103e is separated from the locking block 103d, and the locking and fixing of the wedge block 103e is released. At this time, the driving motor 102a is started to be reversely rotated, so as to realize the recycling of the second protective plate 101c.

[0034] From the above, in use, when the protective plate needs to be extended, the driving motor 102a is started to drive the threaded rod 102b to rotate, thereby driving the second protective plate 101c to slide outward. In the sliding process, the inclined surface of the wedge block 103e is in contact with the inclined surface of the locking block 103d, extruding the locking block 103d, thereby driving the locking block 103d and the sliding plate 103c to slide downward. After sliding, the sliding plate 103c is reset by the elastic force of the reset spring 103f, and the locking block 103d is repositioned into the tooth gap of the wedge block 103e. At this time, the locking block 103d is in contact with the vertical surface of the wedge block 103e, thereby achieving the locking of the wedge block 103e and the second protective plate 101c, and improving the stability of the second protective plate 101c.

[0035] When the second protective plate 101c needs to be recovered at the end of use, the adjusting bolt 103a is rotated in the opposite direction to drive the locking box 103b to slide downward, so that the wedge block 103e is separated from the locking block 103d, and the locking of the wedge block 103e is released. At this time, the driving motor 102a is started in reverse, thereby achieving the recovery of the second protective plate 101c.

[0036] In example two, on the basis of example one, the support 104 includes a mounting bracket 104a arranged on one side of the first protective plate 101a and the second protective plate 101c, a support leg 104b rotatably arranged on one side of the mounting bracket 104a, and a locking bolt 104c threadedly connected to one side of the mounting bracket 104a. The locking bolt 104c is used to lock and adjust the support leg 104b. When needed, the support leg 104b can be locked after being rotated and laid down, and the support leg 104b can be locked when being folded and rotated back after use.

[0037] Further, the support 104 further includes a fixed sleeve 104d fixedly installed on one side of the support leg 104b and a support block 104e slidably arranged on both sides of the fixed sleeve 104d. The support 104 further includes a mounting groove 104f opened on both sides of the support block 104e, a clamping block 104g slidably arranged on the side wall of the mounting groove 104f, a clamping hole 104i opened on the side surface of the fixed sleeve 104d, and a compression spring 104h arranged on the inner side wall of the mounting groove 104f. The two ends of the compression spring 104h are respectively connected to the side wall of the clamping block 104g and the inner side wall of the mounting groove 104f. The clamping block 104g penetrates the clamping hole 104i and is slidably arranged therein. The clamping hole 104i is provided with a plurality of clamping holes and is uniformly distributed on the side wall of the fixed sleeve 104d. Through this arrangement, the support stability of the protective plate can be improved when the support block 104e is pulled out to the two sides after the support leg 104b is laid down. The support block 104e can be quickly pulled out for support and put into the fixed sleeve 104d for recovery through the clamping block 104g, thereby saving the occupation of space.

[0038] Preferably, the height of the support leg 104b on the side of the second protective plate 101c is higher than the height of the support leg 104b on the side of the first protective plate 101a, so that the support legs 104b on both sides can be kept at the same height.

[0039] As can be seen from the above, during use, after the protective plates are unfolded and used, the locking bolt 104c is adjusted, the support leg 104b is rotated and laid down, the bolt 103a is adjusted to lock and fix the support leg 104b, the support block 104e is pulled out to the two sides after the clamping block 104g is pressed, the first protective plate 101a and the second protective plate 101c are supported, the stability of the device is improved, and after use, the clamping block 104g is pressed into the mounting groove 104f, the support block 104e is directly placed into the fixing sleeve 104d for recovery, and then the support leg 104b is rotated to contact the first protective plate 101a and the second protective plate 101c for recovery.
