Embodiment

The embodiment of the utility model is described in detail below in conjunction with attached drawing.

This specific embodiment is only explanation of the invention, it is not the limitation to invention, those skilled in the art The modification of no creative contribution can be made to the present embodiment as needed after this specification is read, but as long as in this hair The protection of Patent Law is all received in bright right.

Embodiment one

A kind of device that can effectively prevent abnormal elevator uplink and tenesmus, including pin hole arranged on lift car and be arranged on The ground lock box of elevator dock floor.

Ground lock box is embedded in the ground of elevator dock floor, including babinet 1 and the ground lock set that is arranged in babinet.Such as Fig. 8, babinet 1 include bottom plate 11 and the cover board 12 being covered on bottom plate 11.Steel nail is squeezed into the left and right sides positioned at bottom plate Ground concrete or wall, babinet is fixed.Squeezing into the steel nail of concrete or wall needs to ensure certain length, in this way, When carriage exception uplink or tenesmus occurs, which can just bear the weight of personnel in whole carriage and carriage, Yi Mianshang Stick up.The top of the internal edge of bottom plate 11 is equipped with the cover board support 111 for being used to support cover board so that cover board 12 can be covered in bottom On plate 11 and its top is just flushed with ground.Cover board should make of the cotton ginning aluminum alloy plate materials of suitable thickness, to ensure Stress and beauty.

Lock 21, push rod 22 and driving member 23 ground lock set with including is equipped with babinet.Wherein, ground lock 21 includes lock housing 211st, the lock tongue 212 and push spring 213 being arranged in lock housing 211.A kind of structure diagram locked with being illustrated in figure 5. Lock housing 211 is fixed on bottom plate by shell bottom plate 2111, and lock housing 211 is equipped with the passage perpendicular to 3 plane of elevator door, lock tongue 212 It is placed in the passage.Lock tongue 212 includes the tapered end 2121 arranged on front end, the lock tail 2122 outside lock housing 211 and positioned at lock Lock body part between first 2121 and lock tail 2122.Push spring 213 is set in outside the lock body part in lock housing 211, is pushed away Spring 213 is sent to be in compressive state under natural conditions so that lock tongue 212 can be in its tapered end 2121 of the promotion of push spring 213 Passage through lock housing is extend out to outside lock housing.The length of tapered end is determined according to the distance between elevator door bead and lift car, is made Obtain tapered end to be inserted into locking car position in the pin hole of lift car correspondence position in the state of stretching, and shrinking When can be fully retracted into lock housing.Or ground lock can also use structure as shown in Figure 6, lock housing 211 passes through shell bottom plate 2111 are fixed on bottom plate, and lock housing 211 is equipped with the passage perpendicular to 3 plane of elevator door, and lock tongue 212 is placed in the passage.Lock tongue 212 include tapered end 2121, the lock tail 2122 positioned at lock housing 211, the spring link 2123 arranged on front end.Two sides of lock housing 211 Face is equipped with the bar hole 2112 set along channel direction.Push spring 213 has two, is separately positioned on the left and right two of lock housing 211 Side.The spring link 2123 of lock tongue 212 through bar hole 2112 connect push spring 213 one end, push spring 213 it is another End is fixedly attached to lock housing 211.Push spring 213 is in compressive state under natural conditions so that lock tongue 212 can be in push bullet Its passage of tapered end 2121 through lock housing of the promotion of spring 213 is extend out to outside lock housing.The length of tapered end is according to elevator door bead and elevator car The distance between railway carriage or compartment and determine so that tapered end is inserted into sedan-chair in the pin hole of lift car correspondence position in the state of stretching Railway carriage or compartment position locks, and can be fully retracted when shrinking into lock housing.

The fixed setting of push rod 22 corresponds at the maximum position that elevator door is opened.As shown in Figure 3,4, push rod 22 is included to turn The upper push-rod 222 and lower push-rod 223, return unit 224 that cylinder 221 is rotated in the opposite sense for axle center.2211 bottom of shaft of rotating cylinder 221 With bottom plate 11 by being welded and fixed, rotating cylinder 221 is set in outside shaft 2211 in portion.Cover board 12 at 221 corresponding position of rotating cylinder with opening Equipped with a U-shaped mouth 121, the other end of rotating cylinder 221 is extend out to outside cover board 12 via U-shaped mouth 121.Upper push-rod 222 is located at cover board 11 （That is lock box 1）On, it is fixedly connected with the top of rotating cylinder 221, lower push-rod 223 is fixed on along the direction opposite with upper push-rod 222 The bottom of rotating cylinder 221.Upper and lower push rod can be rotated in a reverse direction with shaft 221 for axis.Return unit 224 is in stretching shape The side in the close elevator door center of lower push-rod is fixed in the spring that state is set, one end of spring, and the other end of spring is connected to The end of lower push-rod 223.As shown in Figure 1, when elevator door is opened, push rod 22 can be under the pulling of the convergent force of return unit 224 Rotate clockwise so that the upper push-rod 222 on cover board 12 is rotated and is resisted against among elevator door 3, and elevator door is blocked.On The side that push rod 222 is contacted with elevator door 3 is equipped with roller group 2221, and roller group 2221 includes multiple folding sides along elevator door 3 To the high-strength nylon roller of arrangement, and the rotating direction of roller is consistent with the folding direction of elevator door.When elevator door 3 closes When, super middle promotion upper push-rod 222, drives whole push rod to rotate counterclockwise to the position shown in Fig. 2 so that 222 turns of upper push-rod Move that the outside of lift car is parallel with elevator door, while lower push-rod 223 also turns under the drive of upper push-rod 222 and elevator At the parallel position of door.

Driving member 3 includes locking first drive 31 at rear with being arranged on, between the first drive and lower push-rod Second drive 32 and the 3rd drive 33, shackle line 34.The end of lower push-rod 223 and the end of lock tail 2122 are equipped with and use In the steel wire draw ring 341 of connection shackle line 34.One end of shackle line 34 is connected with lower push-rod 223, shackle line 34, successively around the 3rd drive 33, the second drive 32, are finally connected around the 3rd drive 33 with lock tongue 212.Also, make The length of that end shackle line 34 that must be between the first drive 31 and lock tongue 212 and the flexible side of push spring 213 To being consistent.In this way, when the position gone out as shown in Figure 1 under drive of the lower push-rod 223 in upper push-rod 222 is turned to shown in Fig. 2 Position when, the thrust for overcoming push spring 213 is inwardly pulled lock tongue by shackle line 34 so that tapered end 2121 is retracted to lock In shell, to unlock the locking to car position.The position of shackle line 34 and the steel wire draw ring of three drives and lower push-rod It should be installed in same level, to avoid slipping so as to influence the running of whole device.

Such as Fig. 7, cover board 12 is divided into A, B two parts, and part A corresponds to the space that bottom plate supplies push rod 22 to rotate.The present invention's Part A when mounted, is first covered on corresponding bottom plate, is then inserted into part B by ground lock box, in the U-shaped of part B after covering Add one piece of soft rubber dustproof cover on mouth 121.

Each component should all inject lubricating oil to the present apparatus before use, to ensure the flexible motion of each component.Especially lock body And lock portion.In addition, because lift car weight is very big, the present apparatus uses material to use high-quality steel, especially bottom Plate should be advisable with the steel plate of 1cm thickness.

Although being described in conjunction with the accompanying embodiments of the present invention, those of ordinary skill in the art can be in appended power Profit makes various deformations or amendments in the range of requiring.
