DETAILED DESCRIPTION

[0032] See attached Figure 1-7 , reflecting a specific structure of the present invention. The monitoring cross arm for installing the monitoring and detection equipment includes a base 101. The base 101 and the column 102 are also provided with a number of reinforcing plates to improve the overall practicality of the cross arm. The upper end of the base 101 is fixedly provided with a column 102. The interior of the column 102 is provided with a chamber 103. A cross bar 104 is provided on one side of the column 102. The end of the cross bar 104 is provided with a monitoring and detection device 105. The cross bar 104 and the monitoring and detection device 105 are detachably connected to each other, which is convenient for installing and replacing appropriate monitoring and detection equipment 105. A hand is provided at the bottom of the chamber 103. The winch in the example uses a commercially available two-way self-locking hand-cranked winch 200, and other winch structures can also be used. The two-way self-locking hand-cranked winch 200 is used to adjust the length of the cable 5, and the cable 5 drives the cross bar 104 to rotate up and down. A guide pulley mechanism 300 that cooperates with the two-way self-locking hand-cranked winch 200 is provided on the top of the chamber 103. The cross bar 104 is connected to the column 102 through a rotating mechanism 400, which is convenient for adjusting the position of the cross bar 104 and facilitating the downward rotation and retraction operation of the cross bar 104, which can reduce the space occupied by the cross arm and facilitate maintenance and loading and unloading.

[0033] In this example, the crossbar 104 is composed of a single rod section. In other embodiments, if the crossbar 104 is too long, the rod section 104 can be composed of two or more rod sections connected together, and the two rod sections can be connected by a hinge or flange to facilitate assembly and disassembly and maintenance.

[0034] In the example, the guide pulley mechanism 300 includes a first pulley 301 fixedly mounted on the top wall of the chamber 103, and a second pulley 302 is provided on one side of the first pulley 301. The first pulley 301, the second pulley 302, and the third pulley 304 are common guide pulley components on the market, which play a guiding and traction role, and are convenient for changing the direction of force. The second pulley 302 is fixedly connected to the column 102 through the pulley seat 303, and the pulley seat 303 extends to the outside of the column 102, which can avoid the cable 5 from colliding and rubbing with the first hinge seat 401 and the second hinge seat 403 when the cross bar 104 is turned down and retracted, resulting in damage to the components. The third pulley 304 is fixedly provided on the top of the end of the cross bar 104, and an opening 305 is provided on the surface of the column 102 for passing the cable 5. The opening 305 is connected to the chamber 103 to ensure the normal use of the cross arm.

[0035] In the example, the bidirectional self-locking hand winch 200 includes a handle 201, one end of which extends into the interior of the chamber 103 and is connected to a small gear 202. A large gear 203 is meshed with one side of the small gear 202, and a disk 204 is provided at the other end of the large gear 203. The large gear 203 is rotatably connected to the column 102. The large gear 203 and the disk 204 are an integrated structure. A cable drum 205 is provided between the large gear 203 and the disk 204. The cable 5 is wound around the outside of the cable drum 205 to facilitate winding multiple turns of the cable 5. A bidirectional self-locking ratchet pawl assembly 206 is provided corresponding to the small gear 202. When the handle 201 is rotated clockwise / counterclockwise and stops, the pawl of the bidirectional self-locking ratchet pawl assembly 206 engages with the ratchet to achieve the bidirectional self-locking effect of the component.

[0036] In the example, a cable 5 is wound around the outside of the cable drum 205, one end of the cable 5 is connected to the disc 204, and a plurality of circular holes are provided on the surface of the disc 204 to facilitate fixing the end of the cable 5. The other end of the cable 5 passes around the first pulley 301 and extends to the outside of the column 102 through the opening 305, then passes around the second pulley 302 and is fastened to the third pulley 304. At this time, the third pulley 304 acts as a cable end fixing seat to fix the cable end.

[0037] In the example, the rotation mechanism 400 includes a first hinge seat 401 fixedly connected to the column 102, and a left and right rotation shaft 402 is provided on the first hinge seat 401. A second hinge seat 403 is rotatably provided on the left and right rotation shaft 402, so as to facilitate the left and right rotation of the crossbar 104, adapt to the monitoring operation of different monitoring environments, and improve the overall practicality of the crossbar. The interior of the second hinge seat 403 is provided with an upper and lower rotation shaft 404, and a rotation sleeve 405 is rotatably provided on the outer side of the upper and lower rotation shaft 404. The rotation sleeve 405 is fixedly connected to the crossbar 104. The upper and lower rotation shafts 404 on both sides of the crossbar 104 are both provided with bearings for limiting the left and right swing amplitude of the crossbar to prevent the crossbar 104 from swinging left and right. A limit plate for limiting the up and down rotation angle of the crossbar 104 is fixedly provided at the upper end of the second hinge seat 403, which limits the rotation angle of the crossbar 104 to prevent the rotation angle from being greater than 90° when the crossbar 104 is pulled upward.

[0038] During use, the user manually turns the handle 201, thereby driving the small gear 202 and the large gear 203 to engage and transmit, and with the cooperation of the weight of the cross bar 104 and the monitoring and detection equipment 105, the tightening and loosening operations of the cable 5 are realized. When the cross bar 104 needs to be retracted, the cable 5 is in a relaxed state, and the cross bar 104 and the monitoring and detection equipment 105 rotate downward due to the action of gravity, realizing the folding effect of the monitoring cross arm on which the monitoring and detection equipment is installed, which is convenient for the user to operate alone and has good practicality.

[0039] In the example, the cross bar 104 is provided with a pulling rope 6 that drives it to rotate, and a winding wheel that cooperates with the pulling rope 6 is provided on the outside of the column 102. A support frame is provided between the winding wheel and the column 102. The winding wheel and the support frame are fixedly connected by bolts, which is convenient for fixing the length of the pulling rope 6 and facilitating the left and right rotation of the cross bar 104 when it is too long.

[0040] In the example, an insulating seat 106 is fixedly provided on the top of the column 102, and a lightning rod 107 is provided on the upper end of the insulating seat 106 to protect the cross arm, avoid the effects of lightning strikes, and prevent or reduce safety accidents caused by lightning strikes.

[0041] Example 2

[0042] The difference from Example 1 is that Figures 8-10As shown, the guide pulley mechanism 300 also includes a spare fixing seat 306 for fixing the end of the cable. The spare fixing seat 306 is fixedly connected to the column 102, and the spare fixing seat 306 is arranged between the cross bar 104 and the pulley seat 303. When the overall weight of the cross bar 104 and the monitoring and detection equipment 105 is too large, one end of the cable can be fixed on the spare fixing seat 306 after passing through the first pulley 301, the second pulley 302, and the third pulley 304, thereby reducing the force on the cable and the hand winch by about 50%, reducing the probability of friction damage to the cable, and thus extending the service life of the cross arm.

[0043] Among them Figures 8-10 The example also shows a rotation lock assembly for limiting the left and right rotation of the crossbar. The rotation lock assembly includes a spring pin 406 disposed on the first hinge seat 401 and a pin hole on the second hinge seat 403. The spring pin 406 matches the specifications and dimensions of the pin hole. The spring pin 406 is provided with a spring pin control cable 407 for unlocking the lock. An operator on the ground can manually unlock the lock by pulling down the spring pin control cable 407. The end of the spring pin control cable 407 is provided with a fixed ring. The lower end of the column 102 is provided with a hook 408 that cooperates with the fixed ring. The operator can easily hook the fixed ring of the spring pin control cable 407 onto the hook 408 to perform other operations. After removing the fixed ring, the spring pin 406 returns to the locked state under the action of the spring.
