[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a safety protection device for a construction road foundation pit, comprising a base 1; further comprising: a fixing rod 2, the fixing rod 2 being connected to a lifting compartment 9, the lifting compartment 9 being connected to a baffle 1 3, the baffle 1 3 being connected to a grid plate 4, and a baffle 2 6 being provided on one side of the baffle 1 3; a stretching mechanism 5, the stretching mechanism 5 being located on one side of the baffle 1 3, and the stretching mechanism 5 being used to adjust the length of the protection device; a lifting mechanism 7, the lifting mechanism 7 being located inside the lifting compartment 9, and the lifting mechanism 7 being used to adjust the height of the protection device; a fixing mechanism 8, the fixing mechanism 8 being located on one side of the baffle 1 3 and the baffle 2 6, and the fixing mechanism 8 being used to fix the connection between the baffle 1 3 and the baffle 2 6.

[0024] First, the baffle 1 3 and the baffle 2 6 are stretched by the telescopic mechanism to achieve adjustable length of the protective device, and then the height of the protective device can be adjusted by the lifting mechanism 7, and the baffle 1 3 and the baffle 2 6 are fixedly connected by the fixing mechanism 8 to prevent the baffle 1 3 and the baffle 2 6 from opening by themselves during the movement. The length and height adjustable mechanism of the foundation pit guardrail net can adapt to different construction environments, improve construction flexibility, and the guardrail net can be adjusted according to the size of the foundation pit.

[0025] The stretching mechanism 5 includes a telescopic slot 51, which is opened on one side of the baffle 2 6. The telescopic slot 51 is connected to the rotating plate 1 52 and the rotating plate 2 53. The rotating plate 1 52 is connected to the limiting plate 1 54. The other end of the limiting plate 1 54 is connected to one side of the rotating plate 2 53. The other ends of the rotating plate 1 52 and the rotating plate 2 53 are connected to the rotating plate 3 55 and the rotating plate 4 56. The rotating plate 3 55 is connected to the limiting plate 2 57. The other end of the limiting plate 2 57 is connected to one side of the rotating plate 4 56.

[0026] By pulling baffle 1 3, rotating plate 1 52 and rotating plate 2 53 are rotated and stretched, wherein limit plate 1 54 plays a certain reinforcing and limiting role on rotating plate 1 52 and rotating plate 2 53. Pulling baffle 2 6 makes rotating plate 3 55 and rotating plate 4 56 rotate and stretch, playing a stretching role. Limit plate 2 57 plays a fixed limiting role on rotating plate 3 55 and rotating plate 4 56. Setting a length-adjustable mechanism for the foundation pit guardrail net can adapt to different construction environments, improve construction flexibility, and the guardrail net can be adjusted according to the size of the foundation pit.

[0027] The lifting mechanism 7 includes a fixed plate 1 72, which is fixedly connected to one end of the fixed rod 2. The fixed plate 1 72 is connected to a reciprocating screw rod 73, the reciprocating screw rod 73 is connected to a fixed plate 2 74, the fixed plate 2 74 is fixedly connected to the inside of the lifting bin 9, the reciprocating screw rod 73 is connected to a gear 1 75, the gear 1 75 is engaged with a gear 2 76, and one end of the gear 2 76 is connected to a crank 77.

[0028] Turning the crank 77 causes the gear 2 76 to rotate, driving the gear 2 76 to rotate, thereby driving the rotation of the reciprocating screw 73, causing the reciprocating screw 73 to rotate in the middle of the fixed plate 1 72, thereby driving the upward movement of the fixed plate 2 74, thereby driving the upward movement of the lifting warehouse 9, realizing the height adjustment of the protective device, and setting a height-adjustable mechanism for the foundation pit guardrail net, which can adapt to different construction environments and improve construction flexibility. The guardrail net is adjusted according to the size of the foundation pit.

[0029] The fixing mechanism 8 includes a rotating bin 81, which is connected to one side of the baffle 2 6. The rotating bin 81 is provided with an insertion hole 1 82 and an insertion hole 2 83. The rotating bin 81 is connected to a screw 84, which is connected to a rotating rod 85. The rotating rod 85 is located inside the rotating bin 81. A fixing plate 86 is connected to one side of the baffle 1 3. The fixing plate 86 is provided with a fixing hole 1 87 and a fixing hole 2 88.

[0030] When the protective device is no longer needed to be stretched, the screw 84 is turned to rotate the rotating rod 85, which passes through the fixing hole 1 87 in the fixing plate 86, passes through the fixing hole 2 88 again, and is finally inserted into the insertion hole 2 83 to achieve the fixing effect, so that the rotating rod 85 can be better fixed on one side of the arc rod when rotating, avoiding the baffle 1 3 and the baffle 2 6 from opening by themselves during the movement.

[0031] Example 2

[0032] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the first rotating plate 52 and the second rotating plate 53 are in a cross state, and the third rotating plate 55 and the fourth rotating plate 56 are in a cross state.

[0033] The rotating plate 1 52, the rotating plate 2 53, the rotating plate 3 55 and the rotating plate 4 56 are all set to a cross state, so that when the baffle 1 3 and the baffle 2 6 are stretched left and right, the rotating plate 1 52, the rotating plate 2 53, the rotating plate 3 55 and the rotating plate 4 56 are stretched left and right under the connection action of the rotating shaft. The length and adjustable mechanism can adapt to different construction environments and improve construction flexibility. The guardrail net can be adjusted according to the size of the foundation pit, thereby saving time and labor costs.

[0034] Gear 1 75 and gear 2 76 are both bevel gears.

[0035] Gear 1 75 and gear 2 76 are set as umbrella gears to facilitate the engagement of gear 1 75 and gear 2 76, so that the longitudinal rotation of gear 2 76 can better drive the lateral rotation of gear 1 75, thereby realizing the lifting and lowering of the protective device.

[0036] One side of the rotating rod 85 is a straight rod, and the other side is a curved rod.

[0037] One side of the rotating rod 85 is a straight rod and the other side is an arc rod, so that one side of the arc rod can be better fixed between the fixing hole 1 87 and the fixing hole 2 88 when the rotating rod 85 rotates, thereby playing the role of fixing the baffle 1 3 and the baffle 2 6.
