[0027] In order for those skilled in the art to better understand the utility model, the utility model technical scheme is further explained below in combination with the drawings and embodiments.

[0028] Embodiment 1, as Figure 1 and Figure 2The illustrated one kind slope protection construction platform, including base 100, base 100 symmetrically is provided with I-beam slide rail 101, the I-beam slide rail 101 of both sides is jointly slidably connected with lifting tackle 102, base 100 is installed with winch 103, the top of both sides I-beam slide rail 101 is provided with connecting table 104, connecting table 104 is symmetrically provided with first pulley seat 105, the traction rope 106 of winch 103 is passed first pulley seat 105 and is downwardly penetrated connecting table 104 to with lifting tackle 102 fixed connection;Base 100 can be installed with traction vehicle, so that the construction platform can be moved by the traction vehicle construction, both sides I-beam slide rail 101 and the connecting table 104 of top jointly constitute portal frame, by winch 103 winding and unwinding traction rope 106, when winding traction rope 106, lifting tackle 102 can be made along both sides I-beam slide rail 101 to rise, so that the worker in lifting tackle 102 can rise to high place and carry out the construction installation of protective net, when unwinding traction rope 106, under the gravity of lifting tackle 102 and worker, it will move downward, so that lifting tackle 102 and worker are transported from high place to ground;

[0029] Both sides I-beam slide rail 101 are provided with a plurality of anti-falling mechanisms, each anti-falling mechanism is evenly arranged along the longitudinal direction of the I-beam slide rail 101, each anti-falling mechanism comprises a clamping block 110 and a spring rod 111, the clamping block 110 is vertically arranged and slidably connected with the side wall of the I-beam slide rail 101, the side wall of the I-beam slide rail 101 is provided with a sliding sleeve 112 corresponding to the clamping block 110, one end of the spring rod 111 is fixedly connected with the I-beam slide rail 101 and the other end is fixedly connected with the clamping block 110, each clamping block 110 is provided with a through hole corresponding to the traction rope 106, and the traction rope 106 penetrates the through hole of each clamping block 110 from bottom to top.

[0030] When the winch 103 stably pulls the traction rope 106, the traction rope 106 is in a straightened state, and since the traction rope 106 penetrates the through hole of each clamping block 110, the tension of the straightened traction rope 106 will overcome the elastic force of the spring rod 111, so that each clamping block 110 slides relative to the sliding sleeve 112 and exits the I-beam slide rail 101, at this time, under the straightened state of the traction rope 106, each clamping block 110 will not hinder the traction rope 106 to slide the lifting tackle 102 between the two I-beam slide rails 101;

[0031] When any one or both of the traction ropes 106 are accidentally broken, the traction ropes 106 will no longer be taut to generate tension, and thus the respective spring rods 111 corresponding to the traction ropes 106 will quickly rebound under the elastic force, thereby sliding the clamping blocks 110 relative to the sliding sleeves 112 and extending into the I-beam slideway 101, thereby preventing the downward sliding of the lifting trolley 102, and since the clamping blocks 110 are arranged perpendicularly to the side wall surface of the I-beam slideway 101, the clamping blocks 110 will not be pressed out of the I-beam slideway 101 by the gravity of the lifting trolley 102 when extending into the I-beam slideway 101, so that the downward falling of the lifting trolley 102 can be blocked in the emergency situation of accidental breaking of the traction ropes 106, and personal safety accidents caused by falling of the lifting trolley 102 onto the ground can be avoided.

[0032] The utility model discloses a plurality of anti -falling mechanism is set up, when traction rope 106 is broken, the clamping block 110 of anti -falling mechanism can automatically extend into I -beam slideway 101, the downward falling of lifting trolley 102 is blocked, and personal safety accident is avoided.

[0033] As a further description of the embodiment, the thickness of each clamping block 110 gradually increases from top to bottom according to its position height; when the traction rope 106 is broken, the potential energy during the falling of the lifting trolley 102 gradually increases, and therefore the clamping blocks 110 on the lower side are set to have larger thickness to improve the impact resistance; if the clamping blocks 110 on the upper side are broken due to the potential energy during the falling of the lifting trolley 102, the clamping blocks 110 on the lower side with greater impact resistance will be less likely to be broken, thereby further controlling and blocking the falling of the lifting trolley 102.

[0034] Embodiment 2, on the basis of embodiment 1, to increase the activity space of the lifting trolley 102, further improvement is made, as shown in Figures 3 to 5 The side of the lifting trolley 102 away from the I-beam slideway 101 is provided with a sliding cavity, and the lifting trolley 102 is further provided with an expansion mechanism, the expansion mechanism comprising a sliding frame 120, the sliding frame 120 being slidably connected with the sliding cavity, and a positioning assembly and an adjusting assembly being arranged between the sliding frame 120 and the sliding cavity.

[0035] The positioning assembly comprises a positioning sliding block 121 fixedly arranged on one side of the sliding frame 120, and the top of the sliding cavity is provided with a positioning sliding groove 122 matched with the positioning sliding block 122; the adjusting assembly comprises an adjusting block 123 fixedly arranged on the other side of the sliding frame 120, and the other side of the top of the sliding cavity is provided with a strip-shaped groove 124 matched with the adjusting block 123, the strip-shaped groove 124 is provided with mounting tables 125 on both sides, and an adjusting screw rod 126 is rotatably connected between the mounting tables 125, the adjusting screw rod 126 penetrates through the adjusting block 123 and is threadedly rotatably connected with the adjusting block 123, and a compass handle 127 is arranged on one end of the adjusting screw rod 126.

[0036] When it is needed to adjust the activity space of the lifting trolley 102, the worker drives the adjusting screw 126 installed on the mounting table 125 on both sides by operating the compass handle 127, and since the adjusting block 123 is in threaded connection with the adjusting screw 126, the adjusting block 123 can move along the adjusting screw 126, so that the sliding frame 120 can slide out of and slide into the sliding cavity in the lifting trolley 102, and the sliding out of the sliding frame 120 can expand the activity space of the lifting trolley 102, and the positioning sliding block 121 and the positioning sliding groove 122 can be used for auxiliary positioning and keeping the stability of the sliding out and sliding in of the sliding frame 120.

[0037] It should be noted that a plurality of rollers can be arranged on the surface of the sliding frame 120 in the embodiment, so as to reduce the friction between the sliding frame 120 and the sliding cavity in the lifting trolley 102, and facilitate the sliding out and sliding in of the sliding frame 120.

[0040] When the protective net is constructed at a high place and the construction tools need to be supplemented, the worker in the lifting trolley 102 can loosen the locking bolt 136 of the locking sleeve 135, so that the winding roller 134 is no longer locked, at this time, the worker can operate the Z-shaped handle 137 to pay out the pull rope 131 of the winding roller 134, and the tool basket 132 can descend to the ground under the action of gravity, and the worker on the ground can put the required construction tools into the tool basket 132.

[0041] When the construction tool is put into the tool basket 132, the worker in the lifting trolley 102 can reverse rotate the Z-shaped handle 137 to make the winding roller 134 wind the pull rope 131 until the pull rope 131 hoists the tool basket 132 from the ground to the position of the lifting trolley 102, and then the locking bolt 136 is inserted into the locking hole of the winding roller 134 by locking the locking bolt 136 into the locking sleeve 135 again, so that the locking of the winding roller 133 is completed, and the worker in the lifting trolley 102 can take out the construction tool of the tool basket 132 for use.
