Abstract

An up-down integrated escalator that conserves energy by means of gravity for transporting people up and down floors. Said escalator utilizes the weight of the people moving downward to directly offset the weight of the people moving upward, and comprises an up slope (130) and a down slope (140), linked together, formed by a frame (100), combination guide tracks (200), a step belt (300), and determination and control devices (410, 420, 430). The determination and control devices (410, 420, 430) of said escalator checks the people moving upward and the people moving downward, calculates, and makes determinations, so that a drive device can ensure the normal operation of said escalator using the minimum power output. The present invention solves the problem of the existing escalators being able to operate only uni-directionaly, upward or downward, and being unable to directly utilize energy generated from the weight of people moving downward.

Description

 Upward and downward integrated gravitation energy-saving escalators

 Technical field

 The present invention relates to an electric vehicle, and more particularly to an escalator.

 Background technique

The existing escalators run on a slope up and down, and can run from top to bottom or from bottom to top. From the perspective of energy conservation, the existing escalator has two problems:

 1 , because the existing escalator can not know when the full load is not full load, always run at full power consumption.

 2 The power consumption of the escalator when it goes up and when the escalator goes down can be different. The existing escalator runs at the same power consumption.

 3, the weight of the descending personnel is an energy, the existing escalator can not directly turn the energy generated by the descending personnel into the pulling force acting on the upward direction.

 We have consulted the technical solutions of related materials, such as: Chinese patent CN95200818.1 two-way escalator, CN00203760.2 One-piece two-way escalator, CN200420039619.5 A kind of energy-saving escalator for shopping malls. Through analysis, we find that the common feature of these schemes is that it does not change the operation structure of the existing escalator, but converts the downward force into an upward force through a reversing shaft to achieve the purpose of energy saving. The problems with these programs are: 1. In the case of the original operating structure, synchronous operation cannot be achieved. 2, After several turning points, the available force has been basically consumed, and the actual efficiency is not large.

Since the frame, the various guide rails, and the two sides of the pedal are symmetrically identical, only the approximate state of the components in one side is shown in the figure, and the specific details will be described later.

 In the figure, the frame 100 is composed of a front ramp 130 and an upper platform 150 and a rear ramp 140 and a lower connection 160 The connection becomes a loop. 131 is the front bottom slope, which is the entrance of the up pedal 310, and 141 is the rear bottom slope, which is the exit of the down pedal 320. Front slope 130 and rear slope 140 In the 'eight' shape, the top ends of the front slope 130 and the rear slope 140 are connected to both ends of the upper platform 150, and the bottom of the front slope 130 is a forwardly extending front bottom slope 131, the rear slope The bottom of the 140 is a rearwardly extending flat bottom 141. The front end of the lower joint 160 is a semi-circular turn structure with a top end and a rear semi-circular turn structure at the top end.

 The drive rail 250 and the support rail 260 are also closed loops respectively, and the support rails 260 are on the drive rails 250 Inside the ring.

 A front support rail 273 is provided above each of the front ramp support rail 268 and the rear ramp support rail 269. And the rear support rail 274, the top of the front support rail 273 is connected to the top end of the front ramp support rail 268, and the bottom end is connected to the bottom end of the front ramp support rail 268; the rear support rail 274 The top end is connected to the top end of the rear ramp support rail 269, and the bottom end is connected to the bottom end of the rear slope support rail 269.

 In the figure, the pedal belt 300 is on the combined rail 200 When running clockwise backwards, the arrows in the figure indicate the direction of operation. For convenience of explanation, the pedal belt 300 running on the front slope combination rail 210 is referred to as an ascending pedal belt 310. The pedal belt 300 running on the rear ramp combination rail 220 is referred to as a descending pedal belt 320.

It is called the downstream receiver 422. Each receiver 420 only accepts information transmitted by the force sensor 410 running on its respective ramp, i.e., the receiver 420 at the front ramp 130. Only information sent by the force sensor 410 running on the front ramp 130 can be accepted.

As long as someone stands on the descending pedal belt 320, the embodiment of the present invention can be labor-saving according to the principle of the fixed pulley.

 The above is a structural description of the embodiment. The following is a description of the operation of the embodiment.

 The operation of the present invention can be divided into two parts: mechanical operation and discriminant control operation.

 The first part: mechanical operation.

 We explain the operation from three key parts.

 Referring to FIG. 5, FIG. 5 is an up pedal 310 running on the front bottom slope combination rail 211 and the front slope combination rail 210. A schematic view of the section at the bottom.

 The shape of the combination rail 200 is converted from a horizontal to a slanted shape.

 In the figure, the front turn combination guide rail 241 is connected with the front bottom slope combination guide rail 211, and the front bottom flat slope combination guide rail 211 Connected to the front ramp combination rail 210.

 In the figure, the front support rail 273 is above the front ramp support rail 268, supporting the rail upper bearing surface 271 and the support rail lower bearing surface. The bottom ends of the 272 are respectively connected to the support rails 263 on both sides of the lower notch 267.

 It is assumed that the up pedal 310 is now driven by the drive chain belt 520 to start the clockwise combination of the rails from the front and bottom slopes. Run up and back.

 When the pedal 340 is on the front bottom rail combination rail 211, the front support pulley 381 and the rear support pulley 382 In the support rail 260, the tread surfaces 351 of the front and rear pedals 340 are flush.

 When a pedal 340 reaches the bottom of the front ramp combination rail 210, the drive pulley 390 and the rear support pulley 382 The upwardly inclined drive rail 250 and the support rail 260 will start to run upward, at which time the front support pulley 381 of the pedal 340 will leave the support rail lower bearing surface 264 From the lower notch 267 of the support rail upper surface 263, it falls on the support rail lower bearing surface 272 and continues upward, and the rear support pulley 382 of the pedal 340 is under the support rail. 264 runs up synchronously.

 At this time, the up pedal belt 310 running on the front slope combination rail 210 increases with the inclination, and the pedal surface of the latter pedal 340 The 351 is gradually higher than the tread surface 351 of the previous pedal 340, and the front bezel 352 of the latter pedal 340 gradually becomes on the tread surface of the previous pedal 340 351 When the upper pedal strip 310 is running on the front ramp 130, the stepping surface 351 is stepped up and down.

 Referring to FIG. 6, FIG. 6 is an up pedal 310 running on the front slope combination rail 210 and the rear slope combination rail 220. A schematic view of the top section.

 The shape of the combination rail 200 is converted from a tilt to a horizontal direction and then from a horizontal tilt.

 In the figure, the two ends of the upper platform combination rail 230 are combined with the front slope combined rail 210 and the rear slope combined rail 220 The top ends are connected.

 In the figure, the top of the front support rail 273 is a section, and the top end of the support rail lower surface 272 is connected to the upper notch 266 On the support rail upper bearing surface 263, the height of the joint is the same as that of the upper platform support rail lower bearing surface 231.

 Similarly, the top end of the rear support rail 274 is also a section with the top end of the support rail lower bearing 272 attached to the upper notch 266 On the support rail upper bearing surface 263, the height of the joint is the same as that of the upper platform support rail lower bearing surface 231.

 When the pedal 340 is running upward on the inclined track, the transmission pulley 390 is on the lower surface of the drive rail 254, the front support pulley 381 On the support rail lower bearing 272, the rear support pulley 382 is on the support rail under the bearing 264.

 When a pedal 340 is entering the upper platform combination rail 230, the first is the transmission pulley 390 and the rear support pulley. 382, along the drive rail lower bearing surface 254 and the support rail lower bearing surface 264, smoothly enter the horizontal upper platform combination rail 230, at this time, the front support pulley 381 It is also supported on the underside of the guide rail 272.

 While continuing to operate, because the drive pulley 390 and the rear support pulley 382 of the pedal 340 are in a horizontal track, the pedal The 340 can only continue to run backwards horizontally, so the front support pulley 381 will straddle from the upper notch 266 and continue to run on the lower upper platform support rail lower bearing surface 231.

 When the up pedal belt 310 runs to the top of the front slope 130, the foot surface of the front and rear pedals 340 351 The height of the step is gradually reduced. When running on the upper platform combination rail 230, the foot surface 351 is completely flat.

 When the rear support pulley 382 is running, the rear support rail 269 is at the top of the notch 266, because the drive pulley The 390 and front support pulley 381 are also in a horizontal rail that can only continue to run horizontally, and the rear support pulley 382 will pass over the upper gap 266 into the rear support rail 274 Continue to run on the lower bearing surface.

 When entering the top of the rear ramp combination rail 220, the drive pulley 390 and the front support pulley 381 Along the drive rail lower bearing surface 254 and the support rail lower bearing surface 264, the transition smoothly enters the downwardly inclined drive rail 250 and the rear ramp support rail 269, and the rear support pulley 382 It is placed on the support rail lower bearing surface 272 at the top of the rear support rail 274 and is tilted.

 As the rear rail combination rail 220 is tilted downward, the down pedal belt 320 is gradually lowered, and the pedal surface of the latter pedal 340 is gradually lowered. The 351 is gradually lower than the tread surface 351 of the previous pedal 340, and the tailgate 353 of the previous pedal 340 gradually becomes on the tread surface of the rear pedal 340 351 When the upper pedal is exposed and the descending pedal belt 320 is running on the rear slope 140, the stepping surface 351 is stepped in height and height.

 Referring to Figure 7, Figure 7 is a cross-sectional view of the lower pedal 320 running at the bottom of the rear ramp combination rail 140.

 Combination rail 200 The shape is transformed from a slanted shape to a horizontal shape, and then horizontally bent to the lower horizontal shape, and then horizontally bent from the lower side to the upper horizontal shape.

 In the figure, the rear slope combination rail 220 is connected to the rear bottom slope combination rail 221, and then the rear turn combination rail 242 Connection, rear turn combination guide 242 After a 180 degree downward turn, connect with the front turn combination guide 241, refer to Figure 5, and then pass through 180 After the upward turn, the front sloping combination rail 211 is connected.

 In the figure, the rear support rail 274 is above the rear slope support rail 269, supporting the rail upper bearing surface 271 and the support rail lower bearing surface. The bottom ends of the 272 are respectively connected to the support rails 263 on both sides of the lower notch 267.

 When a pedal 340 is approaching the rear sloping combination rail 221, the transmission pulley 390 and the front support pulley 381 From the drive rail lower bearing surface 254 and the support rail lower bearing surface 264, the slope smoothly transitions to the plane to enter the horizontal operation state, and the rear support pulley 382 will bear the bearing surface from the support rail 263 The upper lower notch 267 is worn down and falls on the support rail lower bearing surface 264 to enter the horizontal running state.

 When the pedal belt 300 is moved to the rear bottom slope combination rail 221, the front and rear pedals 340 are stepped on the foot surface 351 Restore to a flat shape.

 When the pedal 340 is moved to the rear turn combination rail 242 of the lower joint rail 240, because of the rear turn combination rail 242 is a downwardly curved semi-circular shape, and the combined pulley 370 is restrained by the rear turn combination guide rail 242, and the pedal 340 is turned over 180 ° to change the running direction to become the stepping surface 351 Continue to move forward.

 After entering the lower connection combination rail 240, the force point of the transmission pulley 390 starts to change on the transmission rail. Above, and the support pulley 380 becomes the balance point, such a structure is advantageous for the light and reliable pedal turning.

 When the pedal 340 is moved to the bottom end of the front turn 241, referring to Fig. 5, the body is turned 180 ° to become the tread surface. The 351 is repeatedly moved up to the front sloping combination rail 211, and the return is in the state of FIG.

 It can be seen from the above description of the drawings of the embodiment that the embodiment can operate normally.

 Can run not equal to already saving effort, if you can't always know the up pedal strap 310 and the down pedal strap 320 The accurate number of personnel, then you can only blindly use the maximum power output maximum power to maintain normal operation, which is not able to save energy and energy.

 The energy saving of the present invention is based on the above-mentioned labor-saving, and is based on this and a complete set of discriminating control device and driving device 500 The cooperation is easy to complete.

 Refer to Figure 8. Figure 8 is a flow chart showing the process of information discrimination and transmission.

 In the figure, the discriminator 430 accepts manual preset speed and direction information 441.

 The discriminator 430 determines the process and method for ensuring the normal operation of the escalator with the minimum output power as follows:

 Suppose there are n load cells 410 because of the force sensor 410 Mounted on each pedal, as long as a person stands on a pedal, the pedal's force sensor 410 sends a message to the receiver 420 on the slope.

 The upstream receiver 421 and the downstream receiver 422 respectively apply the force sensor 410 The transmitted information is accepted, and the information of the force sensor 410 plus its own address coded information is sent to the discriminator 430 at any time.

 Discriminator 430 will receive receiver 420 The sent information is detected, and the load information of the uplink personnel and the downlink personnel in the same time period is detected. If no one returns to the standby state, if someone enters the computing state.

 By calculating and discriminating the received information, an operation information 440 is obtained, and the operation information is transmitted to the driving device 500. Servo circuit 530.

 The running information 440 refers to the minimum output power information for ensuring the normal operation of the escalator in each time period. And the preset preset speed and direction information 441 received.

 The minimum output power information for ensuring the normal operation of the escalator means:

 1 If there are no people at both the upstream and downstream ends, the escalator only needs to output a power that maintains the operation of the device itself. Of course, a better choice should be to stop running and enter standby.

 2 If the number of people on both the upstream and downstream ends is equal, the escalator only needs to output a power that maintains the operation of the device itself. At this time, the power consumed is the same as when no one is at both ends.

 3 If the number of people on the lower end greatly exceeds the number of people on the upper end, the number of people exceeding the number can deduct the power to maintain the operation of the equipment itself, that is, the escalator only needs less power than the above two conditions, and the escalator can be guaranteed to operate normally. .

 4. If the number of people on the uplink is greater than the number of people on the lower end, the power of the escalator can be deducted from the weight of the descendants.

In either case, as long as the specific load conditions of the escalator up and down can be judged, the entire escalator can be operated normally with minimum power.

 Since the conditions of the upstream and downstream personnel are varied, the servo circuit 530 requires the drive unit 500 at each time period. The operation information 440 of the discriminator 430 is accurately executed, and the power of the output, the direction and speed of the operation are modified at any time.
