[0028] 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.

[0029] Example 1:

[0030] See also Figures 1 to 3 , which shows an example scheme of the structure of the comprehensive test tower for fall protection equipment given in this example.

[0031] As can be seen from the figure, the comprehensive test tower for fall protection equipment mainly includes a base 1, the upper end of the base 1 is fixedly connected to a frame 2, and a protective net 3 is provided on the outside of the frame 2; at the same time, an operating door 4 is provided at the rear end of the frame 2, and a protective pad 5 is provided on the upper part of the base 1 on the inner side of the frame 2.

[0032] On the foundation, a bracket 6 is fixedly connected to the end of the frame 2 away from the base 1 (i.e., the top), the inner side of the bracket 6 is fixedly connected to a connecting frame 7, the front end of the connecting frame 7 is fixedly connected to a hanger 8, a hanger 9 is provided at the lower part of the hanger 8, and the end of the hanger 9 away from the hanger 8 is fixedly connected to a tension detector 10, and the end of the tension detector 10 away from the hanger 9 is fixedly connected to a first hook 11 for connecting the fall protection equipment to be tested.

[0033] Furthermore, a winch 12 is fixedly connected to the end (top) of the bracket 6 away from the frame 2, and a wire rope 13 is fixedly connected to the rotating drum of the winch 12; at the same time, a top frame 14 is also fixedly connected to the end of the bracket 6 away from the frame 2, and a fixed pulley 15 is fixedly connected to the side of the top frame 14 close to the bracket 6, and a hook 16 is provided under the bracket 6, and the lower end of the hook 16 is hung with a second hook 17, and the lower end of the second hook 17 is hung with a separation mechanism 18; such a structure is used to connect a dummy wearing fall protection equipment to be tested, so as to lift the dummy to the required test height.

[0034] In some embodiments of this example, the frame 2 and protective net 3 in the integrated test tower are welded together, and the protective net 3 is made of galvanized steel mesh. This configuration of the protective net 3 isolates and protects the test area within the frame 2 during the integrated fall protection equipment test tower. This allows personnel to conduct remote testing from outside the device, while the protective net 3 provides protection against injuries caused by scattered falling objects.

[0035] See also Figure 4 In some embodiments of this example, the hanger 9 in the comprehensive test tower is connected to the hanger 8 by a hook connection, and the hanger 8 is arranged behind the hook 16. Specifically, the hanger 8 is provided with a plurality of connection holes, which are distributed along the length of the hanger 8. Each connection hole is connected to a hanger 9, and the bottom of each hanger 9 is respectively connected to a tension detector 10 and a first hook 11. By configuring the hangers 9 and hangers 8 in this manner, the hanger 8 can be connected to multiple hangers 9 by hook. In this way, multiple pieces of fall protection equipment to be tested can be connected, which allows for multiple tests and improves testing efficiency.

[0036] In some embodiments of this example, the upper end of the hook 16 in the comprehensive test tower is tied to one end of the wire rope 13, and the other end of the wire rope 13 passes through the upper end of the fixed pulley 15 and is wound around the winch 12. Here, the wire rope 13 is provided to connect the winch 12 and the hook 16, and then is directional-transmitted through the fixed pulley 15. In this way, the hoisting height of the hook 16 can be effectively adjusted through the winch 12.

[0037] In this way, when conducting the test, the dummy is dressed in protective equipment, and one end of the fall protection equipment to be tested is connected by the first hook 11, and the dummy wearing the protective equipment is connected by the hook 16 at the same time. The winch 12 is started to drive the hook 16 to move upward, thereby lifting the test dummy until it reaches an appropriate height. The test dummy is released and the dummy falls freely to simulate a falling scene, thereby testing the protective effect of the protective equipment. The tension detector 10 records the tension borne by the protective equipment during the test. The lifting height of the hook 16 can be adjusted according to the test requirements to simulate falling conditions at different heights for a comprehensive test.

[0038] The comprehensive test tower for fall protection equipment formed in this example is provided with a corresponding protective net on the frame 2. In this way, when the comprehensive test tower for fall protection equipment is being carried out, the staff can conduct remote control testing outside the device, and the protective net provides protection to prevent falling objects from scattering and causing injuries to people.

[0039] Example 2:

[0040] This example further provides an optimized solution based on the solution in Example 1.

[0041] See also Figure 5 , which shows a structural scheme of the separation mechanism 18 given in this example.

[0042] As can be seen from the figure, the separation mechanism 18 given in this example specifically includes a housing 1801, a mounting platform 1802, a limiting hole 1803, a motor 1804, a driving gear 1805, a driven gear 1806, a screw 1807, a limiting slider 1808 and a groove 1809.

[0043] Specifically, a mounting platform 1802 is provided inside the shell 1801, and a placement groove 110 is opened on one side of the mounting platform 1802 (as shown on the left side in the figure), and a groove 1809 is provided at the bottom of the mounting platform 1802; a limiting hole 1803 is provided on the side wall of the groove 1809 corresponding to the placement groove 110, and the limiting hole 1803 connects the placement groove 110 and the groove 180, and a limiting groove 1811 is provided on the other side wall of the groove 1809, which corresponds to the limiting hole 1803.

[0044] Furthermore, the limiting hole 1803 is preferably a square limiting hole 1803 with a square cross section.

[0045] A limiting slider 1808 is placed in the limiting hole 1803 on the mounting platform 1802. The limiting slider 1808 is adapted to the limiting hole 1803, and can move along the limiting hole 1803 toward the limiting groove 1811 and be inserted into the limiting groove 1811, thereby cooperating with the groove 1809 to form a locking structure; the limiting slider 1808 can also move along the limiting hole 1803 toward the limiting groove 1811, can detach from the limiting groove 1811, and retract as a whole into the limiting hole 1803, thereby opening the groove 1809.

[0046] The upper end of the mounting platform 1802 of such a structure is fixedly connected to a motor 1804, and the output end of the motor 1804 is fixedly connected to a driving gear 1805. The driving gear 1805 is distributed in the mounting groove 110. At the same time, the driven gear 1806 can also be rotatably mounted in the mounting groove 110, and is located below the driving gear 1805 and meshes with the driving gear 1805.

[0047] A screw rod 1807 is fixedly connected to the middle part of the driven gear 1806. The screw rod 1807 can extend into the limiting hole 1803 and be screwed to the limiting slider 1808 in the limiting hole 1803. In this way, the screw rod 1807 can drive the limiting slider 1808 to move along the limiting hole 1803 toward or away from the limiting groove 1811 by rotating.

[0048] The driving gear 1805 and the driven gear 1806 in the separation mechanism 18 formed in this example are in meshing cooperation, and the driving gear 180 is driven by the motor 1804, and the screw 1807 and the limiting slider 1808 are threadedly connected. The separation mechanism 18 with such a structure can remotely control the operation of the motor 1804, thereby realizing remote control of the separation action state of the separation mechanism 18 and improving the safety of the test.

[0049] Furthermore, the limiting slider 1808 in this example is slidably connected to the limiting hole 1803, and the length of the limiting slider 1808 is slightly larger than the width of the groove 1809, so that it can be inserted into the opposite limiting groove 1811, thereby forming a locking structure in the groove 1809.

[0050] Such a separation mechanism 18 cooperates with the test. When hanging the dummy, the hook at the bottom of the dummy is placed in the groove 1809, and the motor 1804 is started to drive the driving gear 1805 to rotate, thereby driving the driven gear 1806 and the screw 1807 to rotate. The screw 1807 drives the limiting slider 1808 to move along the limiting hole 1803 through rotation until the limiting slider 1808 is inserted into the opposite limiting groove 1811, thereby blocking the groove 1809 and connecting with the dummy.

[0051] On this basis, when the dummy is hoisted to an appropriate height for a fall test, the motor 1804 is started to reverse, and the screw 1807 is driven to drive the limit slider 1808 to move along the limit hole 1803 back to the limit groove 1811 until the limit slider 1808 is completely retracted into the limit hole 1803, and the dummy is released for a fall test. The structure is simple and easy to operate.

[0052] The following is an example of the operation process of the comprehensive test tower for fall protection equipment given in this example.

[0053] Combine Figures 1 to 5 As shown, when the comprehensive test tower for fall protection equipment is used, the dummy is dressed in protective equipment, the first hook 11 is connected to the protective equipment, the hook at the bottom of the dummy is placed in the groove 1809, the motor 1804 is started to drive the driving gear 1805 to rotate, thereby driving the driven gear 1806 and the screw 1807 to rotate, driving the limit slider 1808 to move along the limit hole 1803 until the limit slider 1808 blocks the groove 1809, thereby connecting with the dummy, and the winch 12 is started to drive the hook 16 to move upward, thereby lifting the test dummy until it reaches the appropriate test height;

[0054] The starting motor 1804 drives the limit slider 1808 to move along the limit hole 1803 until the limit slider 1808 is immersed in the limit hole 1803, and the dummy is released. The dummy falls freely to simulate a falling scene, thereby testing the protective effect of the protective equipment. The tension detector 10 records the tension borne by the protective equipment during the test. The lifting height of the hook 16 can be adjusted according to the test requirements to simulate falling conditions at different heights for a comprehensive test.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
