Example one
Fig. 3 is a schematic view showing an installation of the comb plate foreign matter protection device of the present embodiment. The comb plate foreign matter protection device of the embodiment is used for limiting the unexpected displacement of the comb plate 102 of the escalator, the escalator comprises a comb plate 102 and a comb tooth supporting plate 103, the comb plate 102 and the comb tooth supporting plate 103 are fixedly connected on the same plane, it is characterized in that the comb plate foreign matter protection device comprises a first connecting rod 201, a second connecting rod 202, a shifting fork 203, a roller 204 and an electric switch 205, the structure of the shifting fork 203 is specifically referred to FIG. 4, which comprises a fork head 203c and two fork legs (i.e. a first fork leg 203a and a second fork leg 203b), said first fork leg 203a and second fork leg 203b forming a notch, the shifting fork head 203c is positioned outside the notch, one end of the first connecting rod 201 is connected with one side of the comb tooth support plate 103 far away from the comb tooth plate 102, and the other end of the first connecting rod is connected with the shifting fork head 203 c;
the roller 204 is positioned in a notch formed by the first shifting fork leg 203a and the second shifting fork leg 203b and is fixedly connected with one end of the second connecting rod 202; the other end of the second connecting rod 202 is connected with the electrical switch 205, the electrical switch 205 is connected with an electrical loop of the escalator and used for controlling the opening and closing of the electrical loop of the escalator, the electrical switch 205 is installed on the truss 104 of the escalator, and the truss 104 cannot be displaced, so that the electrical switch 205 cannot be influenced;
wherein the fork 203, the roller 204, the second link 202, and the electrical switch 205 are installed in parallel along a first direction, which is a direction of a line (i.e., a direction of x) between the comb plate 102 and the comb support plate 103.
Generally speaking, when the escalator is in operation, when a foreign object is stuck between the step 101 and the comb plate 102, the foreign object will force the comb plate 102 to displace because the step 101 moves toward the comb plate 102 (i.e. the negative direction of x), and the comb support plate 103 will displace as the comb plate 102 because of the fixed connection between the comb support plate 103 and the comb plate 102. It should be understood that the displacement is generally a displacement in the negative x direction, or a positive displacement in the positive y direction, or both in the negative x direction and in the positive y direction.
When the comb plate 102 moves in the negative direction x, the comb support plate 103 pushes the first connecting rod 201 to move in the negative direction x, and then the first fork leg 203a and the second fork leg 203b on the fork 203 push the roller 204 to move in the negative direction x, and finally the second connecting rod 202 pushes the electrical switch 205 to be turned off. When the comb plate 102 moves in the positive direction of y, the comb support plate 103 drives the first connecting rod 201 to move in the positive direction of y, and then the second fork leg 203b on the fork 203 moves in the positive direction of y, the second fork leg 203b pushes the roller 204 to move in the negative direction of x, and finally the second connecting rod 202 pushes the electrical switch 205 to be turned off. When the comb plate 102 is displaced in both the negative x direction and the positive y direction, the electrical switch 205 is also turned off, which will not be described in detail herein.
In addition, the electrical switch 205 is opened when pushed by the second link 202. Since the electrical switch 205 is connected in the electrical circuit of the escalator, when the electrical switch 205 is turned off, the entire escalator stops operating, the steps 101 stop moving, and the comb plate 102 does not further displace, so that the comb plate 102 is not further damaged.
In this embodiment, the first links 201 may be installed in parallel along the first direction, so that the occupied space is small.
One side of the comb tooth support plate 103, which is far away from the comb tooth plate 102, is connected with one end of an elastic element 105, the other end of the elastic element 105 is connected to a truss 104 of the escalator, the elastic element 105 is installed in parallel to the first direction, and the elastic element 105 can be used for resetting the comb tooth plate 102 and the comb tooth support plate 103. When the escalator stops operating, foreign matters are taken out from between the comb plate 102 and the comb support plate 103, and the comb plate 102 and the comb support plate 103 can be reset under the action of the elastic element 105. Of course, the elastic member 105 may use a spring.
In addition, there may be a gap between the roller 204 and the fork legs (i.e. the first fork leg 203a and the second fork leg 203b) of the fork 203, and the comb plate 102 may slightly displace due to vibration of the motor during operation of the escalator, and the gap may prevent the electric switch 205 from being affected by the displacements. Preferably, the size of the gap may be 5 mm.
Preferably, the angle between the two fork legs (i.e. the first fork leg 203a and the second fork leg 203b) may be 90 °. If the included angle is too large, the shifting fork 203 moves along the positive direction of y to easily enable the roller 204 to be separated from the notch; if the angle is too small, the fork 203 requires a longer fork leg to position the roller 204 in the slot.
Example two
Referring to fig. 5, it is a structural diagram of a comb plate foreign matter protection device of an escalator according to the second embodiment of the present invention. The difference from the above embodiment is: first connecting rod 201 includes first montant 201a and first horizontal pole 201b, first montant 201a and first horizontal pole 201b constitute an contained angle (preferably, this contained angle is 90 °), first montant 201a with comb teeth backup pad 103 keeps away from comb plate 102 one side and is connected, first horizontal pole 201b with shifting fork head 203c is connected. In the escalator, the space occupied by the elastic member 105 is large, and if the first link 201 is directly parallel to the first direction as shown in fig. 3, the space occupied by the fork 203 and the roller 204 may affect the elastic member 105. Therefore, the comb plate foreign matter protection device of the embodiment utilizes the first vertical rod 201a and the first horizontal rod 201b to guide the shifting fork 203 and the roller 204 to the position far away from the elastic element 105, and the mutual influence is avoided.
EXAMPLE III
Based on the comb plate foreign matter protection device of the first embodiment or the second embodiment, the present embodiment provides an escalator, which includes a comb plate 102 and a comb support plate 103, one side of the comb plate 102 and one side of the comb support plate 103 are fixedly connected to form a planar structure, and the other opposite side of the comb support plate 103 is provided with the comb plate foreign matter protection device.
In order to improve the safety of the escalator, two comb plate foreign matter protection devices are arranged on the opposite other side of the comb support plate 103, and the two comb plate foreign matter protection devices are symmetrically installed relative to the midpoint of the other side.
To sum up, the utility model discloses a fishback foreign matter protection device and escalator utilizes the shift fork to be connected with the gyro wheel, no matter what kind of direction's displacement takes place for fishback, the shift fork all can promote the gyro wheel and take place the displacement, and then promotes the electrical switch of second connecting rod disconnection escalator, finally close whole escalator, consequently need not to set up fishback foreign matter protection device respectively in perpendicular and fishback and two directions of parallel and fishback, the quantity of electrical switch has also further been reduced, the electric circuit of escalator has been simplified, escalator's security has been strengthened.
