the support frame 1 can be installed in an elevator room corridor, and a sliding rail is arranged in the elevator room corridor along the length direction of the elevator room corridor;

the mounting platform 2 comprises a carriage 21 and a fixed seat 22 mounted on the carriage 21, the carriage 21 comprises a plurality of telescopic rods 211 arranged perpendicular to the direction of the slide rail and vertical rods 212 connected to two sides of the plurality of telescopic rods 211, and the vertical rods 212 are connected to the slide rail in a sliding manner;

the driving device 3 is fixedly arranged on the mounting platform 2 so as to drive the mounting platform 2 to slide on the supporting frame 1 along the length direction of the elevator hoistway;

and the brake anti-falling device 4 is arranged on the mounting table 2.

Firstly, erecting and fixing a support frame 1 in a corridor of an elevator room, standing a worker on an installation platform 2 when installing an elevator and accessories thereof, controlling the installation platform 2 to slide on a slide rail through a driving device 3, and moving to a required installation station; the brake anti-falling device 4 can perform brake, so that the safety accident of workers caused by the direct falling of the mounting table 2 when the driving device 3 fails or an accident occurs is prevented, and the working platform is simple and convenient to use and high in safety; because the stairwell width of each building differs, consequently, the slide rail width of support frame 1 is also different, consequently, in order to adapt to the support frame 1 of the slide rail of different width, balladeur train 21 adopts telescopic link 211, can realize the regulation of transverse width like this to the practicality is stronger.

Specifically, the telescopic rod 211 comprises a fixed rod and a sliding cylinder, and the fixed rod and the sliding cylinder are fixedly connected through a bolt.

Specifically, a telescopic member 213 is hinged between the fixing rod and the vertical rod 212. The provision of the telescopic member 213 further improves the structural strength of the carriage 21. In this embodiment, the telescopic member 213 is a turnbuckle.

Specifically, a telescopic bearing beam 214 for bearing the fixing seat 22 is mounted on the top of the carriage 21. The arrangement of the telescopic carrier beam 214 can facilitate fore-and-aft adjustment of the fixed seat 22 to the space between floors.

Specifically, the driving device 3 includes a lifter 31 and a cable 32, and the cable 32 is connected between the top end of the support frame and the lifter 31.

In particular, the fixed seat 22 is equipped with a safety lock (not shown) for locking and unlocking the cable 32. The safety lock further improves the safety of the working platform and prevents workers from being injured due to the fact that the cable 32 slides down too fast.

Specifically, the carriage 21 is fixedly mounted with a cable slack warning device 23. The device's setting can cause cable 32 to relax in time to report to the police after 4 blocks of brake anti-falling device, avoids mount table 2 to take place to pause and frustrate, and the workman does not have the condition of preventing to receive the injury to take place.

In the present embodiment, the number of the cables 32 is provided with two, one main cable 32 and the other sub cable 32. Therefore, the safety of the working platform is further improved, and when the main cable fails and is broken, the auxiliary cable can be used for lifting.

Specifically, the brake fall preventing device 4 comprises a safety gear 41 which is arranged on the carriage 21 and used for locking the slide rail, and a link mechanism 42 which is arranged on the fixed seat 22 and used for controlling the safety gear 41 to release the slide rail.

When the auxiliary cable is broken, the brake anti-falling device 4 starts protection, and when the driving device 3 stops working, the safety gear 41 is always in a normally closed locking state, so that when the two cables 32 are broken, the mounting table 2 can be stably stopped on the slide rail; during normal work, a worker firstly loosens the safety gear 41 through the link mechanism 42, and then starts the driving device 3 to drive the mounting table 2 to slide.

In this embodiment, the safety gear 41 is a progressive safety gear 41, and two safety gears are provided, and are respectively located on the two side sliding rails of the supporting frame 1, and of course, according to actual conditions, an instantaneous safety gear 41 can also be adopted, so that the effect is better.

Specifically, the fixing seat 22 is further provided with a protection device 5 for preventing the worker from falling due to the missing foot.

Specifically, the protection device 5 includes a guard rail 51 and a safety door 52 fixedly installed on the periphery of the fixing base 22.

Specifically, the safety door 52 includes two door bodies 53 hinged to the guard rail 51, and a door lock 54 is installed between the two door bodies 53.

Because the stairwell width of each building is different, the setting of baffle 56 for the door body 53 is opening the back, under the coordinated action of swinging arms 59, can support baffle 56 and open, and then has filled the space between stairwell and the door body 53, thereby prevents that the workman from falling from this space when the construction, has improved the security.

Specifically, the circumference fixed mounting of fixing base 22 has many spinal branchs vaulting pole 27, many be connected with crossbeam 28 between the bracing piece 27, it has roof 29 to articulate on the crossbeam 28, and is adjacent the side of roof 29 is the butt each other under the action of gravity. The top plates 29 which are mutually abutted form a protection plate, so that parts above the head of a worker can be prevented from falling and causing damage to the body of the worker; and when the mount table 2 falls, the head of a worker wearing the helmet only needs to lightly touch the top plate 29, and the helmet can be opened, so that the situation that the worker cannot open the helmet for escape when the mount table 2 falls is avoided.

In the embodiment, the cross teeth are arranged between the side edges of the top plates 29, so that the contact area between the top plates 29 is increased, and the structural strength is increased.

Specifically, the device further comprises a control module 6 installed on the fixed seat 22, and the driving device 3 is electrically connected with the control module 6.

In particular, the cable slack warning device 23 is electrically connected to the control module 6.

Specifically, a pressure sensor 215 for measuring the load of the fixing base 22 is fixedly mounted on the carriage 21, and the pressure sensor 215 is electrically connected with the control module 6. The pressure sensor 215 can alarm the quality of the fixed seat 22, and when the quality exceeds a preset value, the worker can be reminded, so that overweight is avoided.

Specifically, the link mechanism 42 comprises a brake rod 43 rotatably connected to the carriage 21, the brake rod 43 is connected with a lifting linkage mechanism of the safety tongs 41, a lower crank 44 is fixedly mounted on the brake rod 43, the carriage 21 is hinged with an upper crank 45, one end of the upper crank 45 is provided with a pedal 46, the other end of the upper crank 45 and one end of the lower crank 44 far away from the brake rod 43 are respectively hinged with a connecting rod 47, and the lower end of the connecting rod 47 is connected with a gravity hammer 48; the fixed seat 22 is provided with a first microswitch 221 positioned right below the pedal 46, the brake lever 43 is provided with a butting block 49, and the sliding frame 21 is provided with a second microswitch 216 positioned on the motion track of the butting block 49; the first microswitch 221 and the second microswitch 216 are respectively electrically connected with the control module 6; in a natural state, under the action of gravity of the gravity hammer 48, the first microswitch 221 is separated from the pedal 46, the lower crank 44 is abutted to the second microswitch 216, the second microswitch 216 is in a critical state to be started, and after the pedal 46 is abutted to the first microswitch 221, the first microswitch 221 and the second microswitch 216 are simultaneously switched on, and the control module 6 regulates and controls the safety gear 41 to be released.
