As an improvement, the single door is connected with the balancing weight through a rope or a chain, and the movement direction of the single door is opposite to that of the balancing weight.
As an improvement, the crank comprises a rotating shaft and a hinging seat vertically connected with one end of the rotating shaft, the other end of the rotating shaft is fixedly connected with the small flap door, and one end of the connecting rod is hinged with the crank through the hinging seat.
As an improvement, the upper end welding of ejector pin has the connecting seat, the connecting seat includes U template and establishes the clamp plate in U template upper end, the other end of connecting rod stretches into in the U template and articulated with U template through the round pin axle, the balancing weight is acted on the clamp plate.
As an improvement, the pressure spring is arranged on a spring mounting seat, the spring mounting seat is fixed on the suspension cage, and a through hole for the ejector rod to pass through is arranged on the spring mounting seat.
As an improvement, an adjusting nut is sleeved on the top end of the pressure spring on the ejector rod, and the adjusting nut is in threaded connection with the ejector rod.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model utilizes the balancing weight to be communicated with the single door of the suspension cage, and the balancing weight is linked with the small flap door through the crank connecting rod mechanism, so that the linkage of the single door of the suspension cage and the small flap door is realized, the problem that the single door of the construction lifter needs to be opened manually with the small flap door is solved, and the utility model is safe and reliable.

Detailed Description
The utility model is further described below with reference to the drawings.
As shown in fig. 1 to 3, an automatic small flap door of a construction hoist comprises a driving mechanism 3 for driving the small flap door 2, wherein the driving mechanism 3 comprises a crank 32 arranged at two sides of the small flap door 2, a connecting rod 33 connected with the crank 32, a top rod 38 connected with the connecting rod 33, a pressure spring 36 sleeved on the top rod 38 and a balancing weight 31 linked with a single door 1 of a cage. The balancing weights 31 are arranged at two sides of the door opening of the cage, the single door 1 is connected with the balancing weights 31 through ropes or chains, and the movement direction of the single door 1 is opposite to that of the balancing weights 31; rails for the counterweight 31 to slide up and down can be arranged on both sides of the cage. One end of the crank 32 is fixedly connected with the small flap door 2, the other end of the crank 32 is hinged with one end of the connecting rod 33, the crank 32 comprises a rotating shaft and a hinged seat vertically connected with one end of the rotating shaft, the other end of the rotating shaft is fixedly connected with the small flap door 2, and one end of the connecting rod 33 is hinged with the crank 32 through the hinged seat. The other end of connecting rod 33 is articulated with the upper end of ejector pin 38, the upper end welding of ejector pin 38 has connecting seat 34, connecting seat 34 includes U template 341 and establishes the clamp plate 342 in U template 341 upper end, the other end of connecting rod 33 stretches into in the U template 341 and articulates with U template 341 through the round pin axle, balancing weight 31 effect is on clamp plate 342, ejector pin 38 is perpendicular setting, balancing weight 31 establishes in the top of ejector pin 38, does not influence the rotation of connecting rod 33 when balancing weight 31 effect is on ejector pin 38.
