In order to facilitate the product to move out or in from two sides, the two ends of the supporting piece are provided with outward-expanding edge parts.

Preferably, the first transmission chain and the second transmission chain are both in a chain structure.

In order to play dustproof effect, the first driving chain outside is equipped with the dust cover.

Compared with the prior art, the utility model at least comprises the following advantages:

according to the utility model, the turbine box is adopted to replace a traditional exposed worm gear structure, so that lubricating oil in the turbine box cannot be easily evaporated even in a high-temperature operation environment in the oven, smooth transmission of the worm gear can be effectively ensured for a long time, and the control of the lifting mechanism is more accurate; according to the utility model, the lifting mechanisms are finely distributed, the motor serving as a driving source is arranged outside the oven, so that the circuit arrangement and installation are convenient, and the transmission mechanism is compactly arranged on one side of the storage rack, so that the transmission efficiency is improved; the supporting pieces are the L-shaped supporting rods arranged in groups, so that the product can be stably erected on the top of the supporting pieces, and the stability in the lifting process is facilitated.

Detailed Description

The utility model is described in further detail below with reference to the figures and specific examples.

With reference to fig. 1 to 3, the embodiment discloses an oven lifting mechanism, which specifically includes 1

motor

1, 1

first transmission chain

2, 1

transmission rod

3, 2

article holders

6, 4 turbine boxes 4, 8 second transmission chains 5, and a plurality of supporting members 7.

Specifically, motor 1 adopts gear motor 1, and fixed the setting is on the oven lateral wall, as hoist mechanism's driving source.

The first transmission chain 2 is of a chain structure, the bottom of the first transmission chain is in transmission connection with an output shaft of the motor 1 through a gear meshing structure, and the top of the first transmission chain is also in transmission connection with the transmission rod 3 through the gear meshing structure. First driving chain 2 sets up in the oven outside the same with motor 1, and in order to play dustproof effect, its outside is equipped with the dust cover, and the dust cover can be dismantled and locate on the oven outer wall.

The transmission rod 3 is horizontally arranged and extends to the inside from the outside of the oven, and the inner end of the transmission rod is in transmission connection with the two parallel turbine boxes 4 through a chain and gear structure. The turbine case 4 mainly functions as a speed reduction steering transmission. The two turbine cases 4 are located between two spaced article holders 6 near the front end side. The rear end of each turbine box 4 is close to the rear side of the commodity shelf 6 and respectively drives another turbine box 4, and the output shaft of each turbine box 4 is connected with a group of second transmission chains 5. Every group drive chain has two chain structures of vertical setting, and the interval sets up in supporter 6 both sides about the drive chain of same group, and through pivot looks drive connection, can realize synchronous rotation, and this pivot sets firmly on supporter 6 through the bearing frame.

Furthermore, a plurality of horizontal supporting pieces 7 are arranged between the same group of second transmission chains 5, each supporting piece 7 is a supporting rod with an L-shaped longitudinal section, the end, close to the inner side of the article placing rack 6, of each supporting piece 7 is a horizontal end face, the supporting pieces 7 on the front side and the rear side are arranged in pairs on the same horizontal plane, and the supporting pieces can be used for clamping edges of products to achieve a supporting and bearing effect under the synergistic effect. A set of support piece 7 on the same horizontal plane can bear one and put the thing dish, and supporter 6 is provided with the sensor in a plurality of predetermined high positions for every layer is put the position detection of thing dish, assists second drive chain 5 and will put the accurate promotion of thing dish to each layer target location. Furthermore, the sensor can cooperate with a torque limiter on the first transmission chain 2 to form a fault alarm system, the torque limiter normally works under the condition of normally lifting in place, if the torque limiter is not lifted in place, the load exceeds a set torque value, so that the torque limiter slips, and meanwhile, an alarm signal is sent out to remind a maintainer of paying attention to the torque limiter in time.

Further, in order to facilitate the product to move out or in from both sides, the supporting member 7 is provided with outwardly expanding edge portions 71 at both ends. Specifically, the edge portion 71 is two vertical extending plate structures, the free ends of which are bent outward, and the structures can play a role in guiding and limiting.

It should be noted that the output shafts of the front and rear turbine boxes 4 in the same transmission chain rotate in opposite directions, which makes the second transmission chains 5 on the front and rear sides of the same article placing shelf 6 rotate in opposite directions. Therefore, when the supporting members 7 located on the same horizontal plane at the front side and the rear side of the article placing shelf 6 can rotate along with the respective second transmission chains 5, the supporting members can move upwards from the bottom of the inner side end, turn outwards after reaching the top end and then move downwards, and move to the lower end and enter the next cycle period, so that the continuous lifting mechanism is formed.
